Ted Kremenek ee4e7d4f25 Added special version of ReadPtr() that returns a deserialized pointer 
by value.  This version prohibits backpatching of pointers, so it
useful when a pointee is always known to be deserialized beforehand.

Ted Kremenek 5fe293d7bc Fixed default ctor for APInt to properly initialize BitWidth to a 
non-random value.

Tanya Lattner 5de0daf6b1 Implement the XTARGET feature for PR1778

Ted Kremenek cd0c32865c Augmented ReadPtr and ReadOwnedPtr to control whether or not a pointer is allowed to be backpatched 
or can be registered with the deserializer to backpatch other pointers.

Evan Cheng dd71a5c37b When the allocator rewrite a spill register with new virtual register, it replaces other operands of the same register. Watch out for situations where 
only some of the operands are sub-register uses.

Duncan Sands f042e862fd At the point of calculating the shift amount, the 
type of SV has changed from what it originally was.
However we need the store width of the original.

Evan Cheng 2dbffa4e76 Add pseudo dependency to force two-address instruction to be scheduled after 
other uses. There was a overly restricted check that prevented some obvious
cases.
