Refine predicate of peephole2 to general_reg_operand. [PR target/101743]

The define_peephole2 which is added by r12-2640-gf7bf03cf69ccb7dc
should only work on general registers, considering that x86 also
supports mov instructions between gpr, sse reg, mask reg, limiting the
peephole2 predicate to general_reg_operand.

gcc/ChangeLog:

	PR target/101743
	* config/i386/i386.md (peephole2): Refine predicate from
	register_operand to general_reg_operand.
