Rob Knegjens 4a48531803 py/gc: Reduce code size when MICROPY_GC_SPLIT_HEAP is disabled.
Use C macros to reduce the size of firmware images when the GC split-heap
feature is disabled.

The code size difference of this commit versus HEAD~2 (ie the commit prior
to MICROPY_GC_SPLIT_HEAP being introduced) when split-heap is disabled is:

       bare-arm:    +0 +0.000%
    minimal x86:    +0 +0.000%
       unix x64:   -16 -0.003%

         cc3200:    +0 +0.000%
        esp8266:    +8 +0.001% GENERIC
          esp32:    +0 +0.000% GENERIC

           samd:    -4 -0.003% ADAFRUIT_ITSYBITSY_M4_EXPRESS

The code size difference of this commit versus HEAD~2 split-heap is enabled
with MICROPY_GC_MULTIHEAP=1 (but no extra code to add more heaps):

    unix x64: +1032 +0.197% [incl +544(bss)]

Ayke van Laethem bcc827d695 py/gc: Allow the GC heap to be split over multiple memory areas.
This commit adds a new option MICROPY_GC_SPLIT_HEAP (disabled by default)
which, when enabled, allows the GC heap to be split over multiple memory
areas/regions.  The first area is added with gc_init() and subsequent areas
can be added with gc_add().  New areas can be added at runtime.  Areas are
stored internally as a linked list, and calls to gc_alloc() can be
satisfied from any area.

This feature has the following use-cases (among others):
- The ESP32 has a fragmented OS heap, so to use all (or more) of it the
  GC heap must be split.
- Other MCUs may have disjoint RAM regions and are now able to use them
  all for the GC heap.
- The user could explicitly increase the size of the GC heap.
- Support a dynamic heap while running on an OS, adding more heap when
  necessary.

Yonatan Goldschmidt 2a6ba47110 py/obj: Add static safety checks to mp_obj_is_type().
Commit d96cfd13e3 introduced a regression by breaking existing
users of mp_obj_is_type(.., &mp_obj_bool).  This function (and associated
helpers like mp_obj_is_int()) have some specific nuances, and mistakes like
this one can happen again.

This commit adds mp_obj_is_exact_type() which behaves like the the old
mp_obj_is_type().  The new mp_obj_is_type() has the same prototype but it
attempts to statically assert that it's not called with types which should
be checked using mp_obj_is_type().  If called with any of these types: int,
str, bool, NoneType - it will cause a compilation error.  Additional
checked types (e.g function types) can be added in the future.

Existing users of mp_obj_is_type() with the now "invalid" types, were
translated to use mp_obj_is_exact_type().

The use of MP_STATIC_ASSERT() is not bulletproof - usually GCC (and other
compilers) can't statically check conditions that are only known during
link-time (like variables' addresses comparison).  However, in this case,
GCC is able to statically detect these conditions, probably because it's
the exact same object - `&mp_type_int == &mp_type_int` is detected.
Misuses of this function with runtime-chosen types (e.g:
`mp_obj_type_t *x = ...; mp_obj_is_type(..., x);` won't be detected.  MSC
is unable to detect this, so we use MP_STATIC_ASSERT_NOT_MSC().

Compiling with this commit and without the fix for d96cfd13e3 shows
that it detects the problem.

Damien George d84220b8c6 py/vm: Remove check for ip being NULL when handling StopIteration.
This check for code_state->ip being NULL was added in
a7c02c4538 with a commit message that "When
generator raises exception, it is automatically terminated (by setting its
code_state.ip to 0)".  It was also added without any tests to test for this
particular case.  (The commit did mention that CPython's test_pep380.py
triggered a bug, but upon re-running this test it did not show any need for
this NULL check of code_state->ip.)

It is true that generators that have completed (either by running to their
end or raising an exception) set "code_state.ip = 0".  But there is an
explicit check at the start of mp_obj_gen_resume() to return immediately
for any attempt to resume an already-stopped generator.  So the VM can
never execute a generator with NULL ip (and this was true at the time of
the above-referenced commit).

Furthermore, the other parts of the VM just before and after this piece
of code do require (or at least assume) code_state->ip is non-NULL.

Jim Mussared 8db99f11a7 py/scheduler: De-inline and fix race with pending exception / scheduler.
The optimisation that allows a single check in the VM for either a pending
exception or non-empty scheduler queue doesn't work when threading is
enabled, as one thread can clear the sched_state if it has no pending
exception, meaning the thread with the pending exception will never see it.

This removes that optimisation for threaded builds.

Also fixes a race in non-scheduler builds where get-and-clear of the
pending exception is not protected by the atomic section.

Also removes the bulk of the inlining of pending exceptions and scheduler
handling from the VM. This just costs code size and complexity at no
performance benefit.

Damien George 0db046b67b py/vm: Change comparison for finally handler search from > to >=.
The search in these cases should include all finally handlers that are
after the current ip.  If a handler starts at exactly ip then it is
considered "after" the ip.  This can happen when END_FINALLY is followed
immediately by a finally handler (from a different finally).

Consider the function:

    def f():
        try:
            return 0
        finally:
            print(1)

The current bytecode emitter generates the following code:

    00 SETUP_FINALLY 5
    02 LOAD_CONST_SMALL_INT 0
    03 RETURN_VALUE
    04 LOAD_CONST_NONE              ****
    05 LOAD_GLOBAL print
    07 LOAD_CONST_SMALL_INT 1
    08 CALL_FUNCTION n=1 nkw=0
    10 POP_TOP
    11 END_FINALLY
    12 LOAD_CONST_NONE
    13 RETURN_VALUE

The LOAD_CONST_NONE marked with **** is dead code because it follows a
RETURN_VALUE, and nothing jumps to this LOAD_CONST_NONE.  If the emitter
could remove this this dead code it would produce:

    00 SETUP_FINALLY 4
    02 LOAD_CONST_SMALL_INT 0
    03 RETURN_VALUE
    04 LOAD_GLOBAL print
    06 LOAD_CONST_SMALL_INT 1
    07 CALL_FUNCTION n=1 nkw=0
    09 POP_TOP
    10 END_FINALLY
    11 LOAD_CONST_NONE
    12 RETURN_VALUE

In this case the finally block (which starts at offset 4) immediately
follows the RETURN_VALUE.  When RETURN_VALUE executes ip will point to
offset 4 in the bytecode (because the dispatch of the opcode does *ip++)
and so the finally handler will only be found if a >= comparison is used.

It's a similar story for break/continue:

    while True:
        try:
            break
        finally:
            print(1)

Although technically in this case the > comparison still works because the
extra byte from the UNWIND_JUMP (encoding the number of exception handlers
to unwind) doesn't have a *ip++ (just a *ip) so ip remains pointing within
the UNWIND_JUMP opcode, and not at the start of the following finally
handler.  Nevertheless, the change is made to use >= for consistency with
the RETURN_VALUE change.

Damien George c7271a86ca py/makemoduledefs.py: Remove shebang line and adjust style of comment.
This file is not executable so shouldn't have the shebang line.  This line
can cause issues when building on Windows msvc when the PyPython variable
is set to something other than "python", because it reverts back to using
the shebang line.

The top comment is also changed to """ style which matches all other
preprocessing scripts in the py/ directory.

Damien George cbad559366 py/compile: Give the compiler a hint about num nodes being non-zero.
Without this, newer versions of gcc (eg 11.2.0) used with -O2 can warn
about `q_ptr` being maybe uninitialized, because it doesn't know that there
is at least one qstr being written in to this (alloca'd) memory.

As part of this, change the type of `n` to `size_t` so the compiler knows
it's unsigned and can generate better code.

Damien George f506bf342a py/bc: Remove unused mp_opcode_format function.
This was made redundant by f2040bfc7e, which
also did not update this function for the change to qstr-opcode encoding,
so it does not work correctly anyway.

Damien George b37b578214 py/persistentcode: Remove remaining native qstr linking support.
Support for architecture-specific qstr linking was removed in
d4d53e9e11, where native code was changed to
access qstr values via qstr_table.  The only remaining use for the special
qstr link table in persistentcode.c is to support native module written in
C, linked via mpy_ld.py.  But native modules can also use the standard
module-level qstr_table (and obj_table) which was introduced in the .mpy
file reworking in f2040bfc7e.

This commit removes the remaining native qstr liking support in
persistentcode.c's load_raw_code function, and adds two new relocation
options for constants.qstr_table and constants.obj_table.  mpy_ld.py is
updated to use these relocations options instead of the native qstr link
table.
