[PATCH] Adding target hook allows to reject initialization of register

Some target like RISC-V allow to group vector register as a whole, and only operate part of it in fact, but the 'init-regs' pass will add initialization for uninitialized registers. Add this hook to reject this action for reducing instruction. gcc/ * init-regs.c (initialize_unini
