Remove generating STRUCT_ANON records in PNaCl bitcode files.
Don't generate types for elided cast instructions, since they
are never put into the bitcode file. In addition, do not generate
a type id for the types of global variables, because they are never
needed. Don't allow and STRUCT records in bitcode files
when PNaClVersion==2.
