LoongArch: Use LSX and LASX for block move
gcc/ChangeLog:
* config/loongarch/loongarch.h (LARCH_MAX_MOVE_PER_INSN):
Define to the maximum amount of bytes able to be loaded or
stored with one machine instruction.
* config/loongarch/loongarch.cc (loongarch_mode_for_move_size):
New static function.
(loongarch_block_move_straight): Call
loongarch_mode_for_move_size for machine_mode to be moved.
(loongarch_expand_block_move): Use LARCH_MAX_MOVE_PER_INSN
instead of UNITS_PER_WORD.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/memcpy-vec-1.c: New test.
* gcc.target/loongarch/memcpy-vec-2.c: New test.
* gcc.target/loongarch/memcpy-vec-3.c: New test.
