Sanjay Patel aea884eb82 [Target] move reciprocal estimate settings from TargetOptions to TargetLowering ... 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. The ingredients of this patch are: Remove the reciprocal estimate command-line debug option. Add TargetRecip to TargetLowering. Remove TargetRecip from TargetOptions. Clean up the TargetRecip implementation to work with this new scheme. Set the default reciprocal settings in TargetLoweringBase (everything is off). Update the PowerPC defaults, users, and tests. Update the x86 defaults, users, and tests. Note that if this patch needs to be reverted, the related clang patch checked in at r283251 should be reverted too.
