In machine code, you can't just replaceRegWith() the same way you can
replaceAllUsesWith() in IR.  Virtual registers may have different
register classes that need to be merged first.

Don't use inline assembly in 64-bit Visual Studio. Unfortunately, this means that cpuid leaf 7 can't be queried on versions of Visual Studio earlier than VS 2008 SP1. Fixes PR11147.

profile metadata at the same time. Use it to preserve metadata attached
to a branch when re-writing it in InstCombine.

Add metadata to the canonicalize_branch InstCombine test, and check that
it is tranformed correctly.
