PNaCl bitcode: Remove handling of named struct types

Named struct types should not appear in LLVM IR that passes the PNaCl
ABI verifier.

Remove the test struct-types.ll because it no longer passes.

Handling of TYPE_CODE_STRUCT_ANON must remain for now until this issue
is fixed: https://code.google.com/p/nativeclient/issues/detail?id=3648

BUG=https://code.google.com/p/nativeclient/issues/detail?id=3590
TEST=PNaCl toolchain trybots
