1.Added dg-do compile on LoongArch.
When binutils does not support vector instruction sets, an error occurs
because the assembler does not recognize vector instructions.
2.Added "-mlsx" option for vectorization on LoongArch.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/gen-vect-2.c: Added detection of compilation
behavior and "-mlsx" option on LoongArch.
* gcc.dg/tree-ssa/gen-vect-25.c: Dito.
