Summary: [AST] Fix for core in test_grammar.py

Initial Comment:
Executing statements like:

compile("lambda x:x=1")

is causing a coredump on windows when it attempts to 
free an uninitialized ast_sequence.  Making sure that an 
appropriate null value is added to the sequence before 
cleaning up fixes this.

I think your fix only works when the length of the sequence
is one.  I checked in a different fix (i.e. initialize to
NULLs when allocating a new asdl_seq).  test_grammar now passes.
