circuitpython/py/runtime0.h
Damien George 323d47887f py/runtime: Reorder some binary ops so they don't require conditionals.
runtime0.h is part of the MicroPython ABI so it's simpler if it's
independent of config options, like MICROPY_PY_REVERSE_SPECIAL_METHODS.

What's effectively done here is to move MP_BINARY_OP_DIVMOD and
MP_BINARY_OP_CONTAINS up in the enum, then remove the #if
MICROPY_PY_REVERSE_SPECIAL_METHODS conditional.

Without this change .mpy files would need to have a feature flag for
MICROPY_PY_REVERSE_SPECIAL_METHODS (when embedding native code that uses
this enum).

This commit has no effect when MICROPY_PY_REVERSE_SPECIAL_METHODS is
disabled.  With this option enabled this commit reduces code size by about
60 bytes.
