LoongArch: Use simplify_gen_subreg instead of gen_rtx_SUBREG in loongarch_expand_vec_cond_mask_expr [PR112476]
GCC internal says:
'subreg's of 'subreg's are not supported. Using
'simplify_gen_subreg' is the recommended way to avoid this problem.
Unfortunately loongarch_expand_vec_cond_mask_expr might create nested
subreg under certain circumstances, causing an ICE.
Use simplify_gen_subreg as the internal document suggests.
