Alessandro Gatti 1df86516e0 py/asmrv32: Reserve a flag for the Zcmp RV32 CPU extension. ...

This commit performs the necessary changes to handle an additional RV32
CPU extension flag, for the Zcmp extension in this case.

The changes are not limited to RV32-only code, as other parts of the
tooling need to be modified for this: the testing framework has to be
made aware that an extra bit can be set in sys.implementation._mpy and
needs to know how it is called, and "mpy-cross" must be able to actually
set that flag bit in the first place via the appropriate command line
argument.
