Now that -loop-idiom uses TargetLibraryInfo properly, it doesn't
need to be pulled out of the pass manager when the user specifies -fno-builtin. It can intelligently determine which libcalls to optimize based on what is enabled in TargetLibraryInfo. This allows -fno-builtin-foo to work someday. llvm-svn: 125981
