LoongArch: Increase cost of vector aligned store/load.
Based on SPEC2017 performance evaluation results, it's better to make them equal
to the cost of unaligned store/load so as to avoid odd alignment peeling.
gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_builtin_vectorization_cost): Adjust.
