Summary: [AST] Generator expressions

Initial Comment:
Adds generator expression support to the AST branch. 
Support is sufficient to allow test_grammar to pass. 
 
Also eliminates the display of interim results within functions 
compiled at the interactive prompt, and the allocation of large 
amounts of memory when zero is passed to asdl_seq_new.

I did wonder about that, but the assert wasn't triggering
for me. The offending line is REQ(n, testlist_gexpr) in
ast_for_genexp.

I'll setup a debug build to check all of the assertions
properly.

This triggers an assert with a genexp in an argument because
the node is not a testlist_gexp, e.g. foo(i for i in
range(5)).  It's unclear what to do with foo(a = i for i in
range(5); see bug # 1167751
