Chrome build broken on current

[Jeff Roberson]

The IDL parser seems to be out of sync with the python flex/yacc package. 
I can get past this by editing ppapi/generators/idl_{lexer,parser}.py and 
not passing in None for the tables.  After that it fails because we're not 
compiling assembly sources and there are a ton of unresolved symbols 
related to sse2/3 support.

Is anyone working on this?

Thanks,
Jeff
