[AArch64] Fix bogus MOVPRFX warning for GPR form of CPY
One of the MOVPRFX tests has:
output register of preceding `movprfx' used as input at operand 3 -- `cpy z1.d,p1/m,x1'
But X1 and Z1 are not the same register, so the instruction is
actually OK.

opcodes/
* aarch64-opc.c (verify_constraints): Skip GPRs when scanning the
registers in an instruction prefixed by MOVPRFX.
gas/
* testsuite/gas/aarch64/sve-movprfx_25.s: Allow CPY Z1.D.P1/M,X1
to be prefixed by MOVPRFX.
* testsuite/gas/aarch64/sve-movprfx_25.d: Update accordingly.
* testsuite/gas/aarch64/sve-movprfx_25.l: Likewise.
