LoongArch: Optimize vector constant extract-{even/odd} permutation.
For vector constant extract-{even/odd} permutation replace the default
[x]vshuf instruction combination with [x]vilv{l/h} instruction, which
can reduce instructions and improves performance.
gcc/ChangeLog:
* config/loongarch/loongarch.cc (loongarch_is_odd_extraction):
Supplementary function prototype.
(loongarch_is_even_extraction): Adjust.
(loongarch_try_expand_lsx_vshuf_const): Adjust.
(loongarch_is_extraction_permutation): Adjust.
(loongarch_expand_vec_perm_const_2): Adjust.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/lasx-extract-even_odd-opt.c: New test.
