  When GCC is able to detect vectorized test cases in the common layer, FAIL
entries appear in some test cases after regression testing. The cause of the
error is that the vectorization option was not set when testing the program,
and the vectorization code could not be generated, so additional support for
the "-mlsx" option needed to be added back on the LoongArch architecture.

gcc/testsuite/ChangeLog:

	* gcc.dg/signbit-2.c:Added additional "-mlsx"
	compilation options.
	* gcc.dg/tree-ssa/scev-16.c:Dito.
	* gfortran.dg/graphite/vect-pr40979.f90:Dito.
	* gfortran.dg/vect/fast-math-mgrid-resid.f:Dito.
