[PATCH] D54649: [FPEnv] Rough out constrained FCmp intrinsics

[Cameron McInally via Phabricator via llvm-commits]

This is a continuation of the abandoned https://reviews.llvm.org/D54121...

Here's a big patch for the constrained FCmp intrinsics. There's a lot here, so I did not include the full set of constrained FCmp intrinsics or tests yet. I intend to add those in a separate patch.

These intrinsics will require some auxiliary constructs in TableGen, which make up the bulk of this code. Those are:

- any_bool_ty
- LLVMScalarOrVectorSameWidth

I'll also point out some things that I'm unsure about inline. Hopefully others are more familiar with that code.
