[issue23896] lib2to3 doesn't provide a grammar where exec is a function

[Eli Bendersky]

New submission from Eli Bendersky:

lib2to3 helpfully provides pygram.python_grammar_no_print_statement for parsing 
Python 3 ('print' has the semantics of an identifier, not a keyword)

However, the same courtesy is not extended to 'exec', which also turns from a 
statement to an identifier in Python 3.

I'd propose adding something like python_grammar_no_print_and_exec_statement 

The name's a handful, but it's explicit and I can't think of anything else, 
given that we don't want to change the lib2to3 API at this time to rename these 
grammars using some other convention.
