This allows a port to specify exactly how many bits are in a small
int (eg for a uPy bytecode cross compiler).

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.

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.

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.

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.
