As preparation for removing the getSubtargetImpl() call from TargetMachine go ahead and flip the switch on caching the function dependent subtarget and remove the bare getSubtargetImpl call from the X86 port. As part of this add a few tests that show we can generate code and assemble on X86 based on features/cpu on the Function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232879 91177308-0d34-0410-b5e6-96231b3b80d8
