was inserted or not. This allows bitcast in fast isel to properly handle the case

Also, if LV isn't around, then TwoAddr doesn't need to be updating flags, since they won't have been set in the first place.

Fix a problem where lib/Target/TargetInstrInfo.h would include and use
...
a header file from libcodegen. This violates a layering order: codegen
depends on target, not the other way around. The fix to this is to
split TII into two classes, TII and TargetInstrInfoImpl, which defines
stuff that depends on libcodegen. It is defined in libcodegen, where
the base is not.

from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
