[PATCH] D38482: TargetMachine: Use LLVMTargetMachine in CodeGen

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

And for what it's worth for some of the methods I moved around here:

- `usesPhysRegsForPEI()` this one should be possible to eliminate with some refactoring where we factor out register scavenging into a separate pass from PEI. (That's somewhere on my TODO list not very high up though).
- `useIPRA()` this one could just as well be a know in TargetPassConfig.
