[AArch64] Correctly detect X reg from W reg in isCopyImpl (#137348)
The MachineCopyPropagation pass was incorrectly removing copy (ORRWrs)
instruction that appeared to be a nop. The instruction should not have
been marked as a copy though, the code was incorrectly assuming that
w29 - w0 + x0 == x29, but as x29 is fp it was out of order with the other
registers.
Fixes an issue reported on #129889.
