[XCore] Fix instruction selection for zext, mkmsk instructions.
r182680 replaced CountLeadingZeros_32 with a template function
countLeadingZeros that relies on using the correct argument type to give
the right result. The type passed in the XCore backend after this
revision was incorrect in a couple of places.
Patch by Robert Lytton.
