Use the proper clobber check in handleLiveInRegister().

When a physreg is live in to a basic block, look for any instruction in
the block that clobbers the physreg.

The instruction doesn't have to properly redefine the register, any
overlapping clobber is OK.

This slightly changes live ranges when compiling with register masks.
