This brings the compile time of Function.cpp from ~40s down to ~4s for me locally. It also shaves off about 400KB of object file size in a release+asserts build. I also realized that the AMDGPU backend does not have any GCC builtin names to match, so the extra lookup was a no-op. I removed it to silence a zero-length string table array warning. There should be no functional change here. This change really ends the story of PR11951. llvm-svn: 258897
