commit r15-2878-g0498f8bda1d08b8ed8100d759917792baf2da15f

LoongArch: Drop vcond{,u} expanders.
Optabs vcond{,u} will be removed for GCC 15. Since regtest shows no
fallout, dropping the expanders, now.
gcc/ChangeLog:
PR target/114189
* config/loongarch/lasx.md (vcondu<LASX:mode><ILASX:mode>): Delete.
(vcond<LASX:mode><LASX_2:mode>): Likewise.
* config/loongarch/lsx.md (vcondu<LSX:mode><ILSX:mode>): Likewise.
(vcond<LSX:mode><LSX_2:mode>): Likewise.
