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.

building more module variants (overall), but it allows configuration
macros such as NDEBUG to work so long as they're specified via command
line. More to come in this space.

Fixed merge-mistake where ActOnAccessSpecifier was called twice for every access specifier. The testcase has been changed to catch this too.

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.

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