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