AsmParser: restore LLVM IR compatibility for linker_private{,_weak}
This restores the linker_private and linker_private_weak lexemes to permit
translation of the deprecated lexmes. The behaviour is identical to the bitcode
handling: linker_private and linker_private_weak are handled as if private had
been specified. This enables compatibility with IR generated by LLVM 3.4.
