py/parse: Remove old esp32 compiler workaround.

Browse Source 
The ESP32 port contains a workaround to avoid having a certain function
in `py/parse.c` being generated incorrectly.  The compiler in question
is not part of any currently supported version of ESP-IDF anymore, and the
problem inside the compiler (well, assembler in this case) has been
corrected a few years ago.

This commit removes all traces of that workaround from the source tree.
