[AArch64] PR 68102: Check that operand is REG before checking the REGNO in mov-immedi...

	PR target/68102
	* config/aarch64/aarch64.md (*movsi_aarch64): Check that
	operands[0] is a reg before taking its REGNO in split condition.
	(*movdi_aarch64): Likewise.

	* gcc.target/aarch64/pr68102_1.c: New test.
