By default, vectorization is not enabled on LoongArch,

Hmm, but wouldn't every test in the vect/ directory automatically get -
mlsx (from DEFAULT_VECTCFLAGS in lib/target-supports.exp)?
This is indeed the case. The reason for the error is that the default
options are
overwritten by using 'dg-options' in these two test cases.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/pr112325.c: Add the vector compilation
option '-mlsx' for LoongArch.
* gcc.dg/vect/pr117888-1.c: Likewise.
