71019ae4f5 py/grammar: Group no-compile grammar rules together to shrink tables. 
Grammar rules have 2 variants: ones that are attached to a specific
compile function which is called to compile that grammar node, and ones
that don't have a compile function and are instead just inspected to see
what form they take.

In the compiler there is a table of all grammar rules, with each entry
having a pointer to the associated compile function.  Those rules with no
compile function have a null pointer.  There are 120 such rules, so that's
120 words of essentially wasted code space.

By grouping together the compile vs no-compile rules we can put all the
no-compile rules at the end of the list of rules, and then we don't need
to store the null pointers.  We just have a truncated table and it's
guaranteed that when indexing this table we only index the first half,
the half with populated pointers.

This patch implements such a grouping by having a specific macro for the
compile vs no-compile grammar rules (DEF_RULE vs DEF_RULE_NC).  It saves
around 460 bytes of code on 32-bit archs.

e6003f466e py: De-optimise some uses of mp_getiter, so they don't use the C stack. 
In these cases the heap is anyway used to create a new object so no real
need to use the C stack for iterating.  It saves a few bytes of code size.

f4df3aaa72 py: Allow bytecode/native to put iter_buf on stack for simple for loops. 
So that the "for x in it: ..." statement can now work without using the
heap (so long as the iterator argument fits in an iter_buf structure).

ae8d867586 py: Add iter_buf to getiter type method. 
Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset

Allows to call the following without heap memory:
- all, any, min, max, sum

TODO: still need to allocate stack memory in bytecode for iter_buf.

05a4859585 stmhal: Implement a proper thread scheduler. 
This patch changes the threading implementation from simple round-robin
with busy waits on mutexs, to proper scheduling whereby threads that are
waiting on a mutex are only scheduled when the mutex becomes available.

f6c22a0679 py/vm: Add MICROPY_PY_THREAD_GIL_VM_DIVISOR option. 
This improves efficiency of GIL release within the VM, by only doing the
release after a fixed number of jump-opcodes have executed in the current
thread.

234f07f16c py/modthread: Use system-provided mutexs for _thread locks. 
It's more efficient using the system mutexs instead of synthetic ones with
a busy-wait loop.  The system can do proper scheduling and blocking of the
threads waiting on the mutex.

2847d7431d tests/thread: Replace busy waiting loops with a loop that sleeps. 
Depending on the thread scheduler, a busy-wait loop can hog the CPU and
make the tests very slow.  So convert such loops to loops that have an
explicit sleep, allowing the worker threads to do their job.
