[PATCH] D73495: [CodeGen] Attach no-builtin attributes to functions with no Decl

thegameg added a project: clang.

When using -fno-builtin[-<name>], we don't attach the IR attributes to functions with no Decl.

This results in projects using -fno-builtin or -ffreestanding to start seeing symbols like _memset_pattern16.

The fix changes the behavior to always add the attribute if LangOptions requests it.
