Tim Northover da0416b935 X86: change zext moves to use sub-register infrastructure.
32-bit writes on amd64 zero out the high bits of the corresponding 64-bit
register. LLVM makes use of this for zero-extension, but until now relied on
custom MCLowering and other code to fixup instructions. Now we have proper
handling of sub-registers, this can be done by creating SUBREG_TO_REG
instructions at selection-time.

Should be no change in functionality.
