It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

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.

Move isLoadFrom/StoreToStackSlot from MRegisterInfo to TargetInstrInfo,a far more logical place. Other methods should also be moved if anyoneis interested. :)
