Handle regmasks in findRegisterDefOperandIdx().
...
Only accept register masks when looking for an 'overlapping' def. When
Overlap is not set, the function searches for a proper definition of
Reg.
This means MI->modifiesRegister() considers register masks, but
MI->definesRegister() doesn't.

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.
