54729247e1 minimal: Add enough code to run minimal build on STM32F4xx hardware. 
Minimal support code for a Cortex-M CPU is added, along with set-up
code for an STM32F4xx MCU, including a UART for a REPL.  Tested on
a pyboard.  Code size is 77592 bytes.

daa1a455c6 stmhal: Remove custom mod_machine_mem_get_{read,write}_addr functions. 
They are no longer needed because stm constants can now be 32 bits wide.

2621f8a340 stmhal: Make stm constants big ints when they don't fit in a small int. 
Adds 924 bytes of code, but means that no more hacks and work-arounds are
needed due to large constants becoming negative.

ea8be373a9 py/inlinethumb: Remove 30-bit restriction on movwt instruction.

22b2265053 py/parse: Improve constant folding to operate on small and big ints. 
Constant folding in the parser can now operate on big ints, whatever
their representation.  This is now possible because the parser can create
parse nodes holding arbitrary objects.  For the case of small ints the
folding is still efficient in RAM because the folded small int is stored
inplace in the parse node.

Adds 48 bytes to code size on Thumb2 architecture.  Helps reduce heap
usage because more constants can be computed at compile time, leading to
a smaller parse tree, and most importantly means that the constants don't
have to be computed at runtime (perhaps more than once).  Parser will now
be a little slower when folding due to calls to runtime to do the
arithmetic.

d6b31e4578 py: Change mp_obj_int_is_positive to more general mp_obj_int_sign.

93b3726240 py/parse: Optimise away parse node that's just parenthesis around expr. 
Before this patch, (x+y)*z would be parsed to a tree that contained a
redundant identity parse node corresponding to the parenthesis.  With
this patch such nodes are optimised away, which reduces memory
requirements for expressions with parenthesis, and simplifies the
compiler because it doesn't need to handle this identity case.

A parenthesis parse node is still needed for tuples.

3ea03a1188 py/gc: Improve mark/sweep debug output. 
Previously, mark operation weren't logged at all, while it's quite useful
to see cascade of marks in case of over-marking (and in other cases too).
Previously, sweep was logged for each block of object in memory, but that
doesn't make much sense and just lead to longer output, harder to parse
by a human. Instead, log sweep only once per object. This is similar to
other memory manager operations, e.g. an object is allocated, then freed.
Or object is allocated, then marked, otherwise swept (one log entry per
operation, with the same memory address in each case).
