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
