[LLVMdev] Embedding cpu and feature strings into IR and enabling switching subtarget on a per function basis
I've been investigating what is needed to ensure command line options are
passed to the backend codegen passes during LTO and enable compiling
different functions in a module with different command line options (see
the links below for previous discussions).

[LLVMdev] Enable changing UnsafeFPMath on a per-function basis
...ree that I shouldn't proceed with my current plan. I think exposing fp
flags in selection dag needs a little more work than r210467 (which exposed
nsw and nuw) did. In particular, some of the targets set operation actions
based on the value of TargetOptions::UnsafeFPMath (see
X86TargetLowering::resetOperationActions), which means legalization has to
examine the flags in addition to the opcode and type to get the operation
action.
