Commit Message

  When gcc enabled the vectorization of the common layer, some FAIL items
appeared in GCC regression tests, such as gcc.dg/fma-{3,4,6,7}.c. On LoongArch
architecture, for example, the result of fmsub.s instruction is a*b-c, and
there is a problem of positive and negative zero inequality between the result
of c-a*b expected to be calculated, so the detection of such problems in
LoongArch architecture needs to be set to unsupported state.

gcc/testsuite/ChangeLog:

	* gcc.dg/fma-3.c:The intermediate file corresponding to the
	function does not produce the corresponding FNMA symbol, so the test
	rules should be skipped when testing.
	* gcc.dg/fma-4.c:The intermediate file corresponding to the
	function does not produce the corresponding FNMS symbol, so skip the
	test rules when testing.
	* gcc.dg/fma-6.c:The cause is the same as fma-3.c.
	* gcc.dg/fma-7.c:The cause is the same as fma-4.c
