42e0c59308 py: Add MICROPY_COMP_{DOUBLE,TRIPLE}_TUPLE_ASSIGN config options. 
These allow to fine-tune the compiler to select whether it optimises
tuple assignments of the form a, b = c, d and a, b, c = d, e, f.
Sensible defaults are provided.

ddd1e18801 py: Add config option MICROPY_COMP_MODULE_CONST for module consts. 
Compiler optimises lookup of module.CONST when enabled (an existing
feature).  Disabled by default; enabled for unix, windows, stmhal.
Costs about 100 bytes ROM on stmhal.

1e9a92f84f py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled. 
Going from MICROPY_ERROR_REPORTING_NORMAL to
MICROPY_ERROR_REPORTING_TERSE now saves 2020 bytes ROM for ARM Thumb2,
and 2200 bytes ROM for 32-bit x86.

This is about a 2.5% code size reduction for bare-arm.

3c658a4e75 py: Fix bug where GC collected native/viper/asm function data. 
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

7e4ec3bf4f bare-arm: Hint of setting MICROPY_ERROR_REPORTING to REPORTING_TERSE. 
Commented out so far, as enabled leads to dozen more bytes used actually
(due to string pooling effects).
