[clang] make reciprocal estimate codegen a function attribute The motivation for the change is that we can't have pseudo-global settings for codegen living in TargetOptions because that doesn't work with LTO. Ideally, these reciprocal attributes will be moved to the instruction-level via FMF, metadata, or something else. But making them function attributes is at least an improvement over the current state. I'm committing this patch ahead of the related LLVM patch to avoid bot failures, but if that patch needs to be reverted, then this should be reverted too.
