Daniel Sanders dfca98d6a8 [mir-strip-debug] Optionally preserve debug info that wasn't from debugify/mir-debugify
Summary:
A few tests start out with debug info and expect it to reach
the output. For these tests we shouldn't strip the debug info

Daniel Sanders a79b2fc44b Add pass to strip debug info from MIR
Summary:
Removes:
* All LLVM-IR level debug info using StripDebugInfo()
* All debugify metadata
* 'Debug Info Version' module flag
* All (valid*) DEBUG_VALUE MachineInstrs
* All DebugLocs from MachineInstrs

This is a more complete solution than the previous MIRPrinter
option that just causes it to neglect to print debug-locations.

* The qualifier 'valid' is used here because AArch64 emits
  an invalid one and tests depend on it
