Test failures in gcc.target/i386/xorps-sse2.c were observed due to unexpected assembler output for pxor and xorps instructions when a particular SSE optimization was enabled. This commit modifies the test case to explicitly disable the sse_packed_single_insn_optimal tune-control knob, resolving the assembler scan failures.
