Dan Gohman eabd647cd5 Change target-specific classes to use more precise static types. 
This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

Evan Cheng 3b3286d4bc 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.

Owen Anderson 2a3be7bb6c Move even more functionality from MRegisterInfo into TargetInstrInfo. 
Some day I'll get it all moved over...

Chris Lattner 25568e4cef 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.

Owen Anderson 7a73ae9a86 Move copyRegToReg from MRegisterInfo to TargetInstrInfo. This is part of the

Chris Lattner bb53acd03c Move isLoadFrom/StoreToStackSlot from MRegisterInfo to TargetInstrInfo,a far more logical place. Other methods should also be moved if anyoneis interested. :)
