LoongArch: Fix ICE when passing two same vector argument consecutively

Following code will cause ICE on LoongArch target:

  #include <lsxintrin.h>

  extern void bar (__m128i, __m128i);

  __m128i a;

  void
  foo ()
  {
    bar (a, a);
  }

It is caused by missing constraint definition in mov<mode>_lsx. This
patch fixes the template and remove the unnecessary processing from
loongarch_split_move () function.

This patch also cleanup the redundant definition from
loongarch_split_move () and loongarch_split_move_p ().

gcc/ChangeLog:

	* config/loongarch/lasx.md: Use loongarch_split_move and
	loongarch_split_move_p directly.
	* config/loongarch/loongarch-protos.h
	(loongarch_split_move): Remove unnecessary argument.
	(loongarch_split_move_insn_p): Delete.
	(loongarch_split_move_insn): Delete.
	* config/loongarch/loongarch.cc
	(loongarch_split_move_insn_p): Delete.
	(loongarch_load_store_insns): Use loongarch_split_move_p
	directly.
	(loongarch_split_move): remove the unnecessary processing.
	(loongarch_split_move_insn): Delete.
	* config/loongarch/lsx.md: Use loongarch_split_move and
	loongarch_split_move_p directly.

gcc/testsuite/ChangeLog:

	* gcc.target/loongarch/vector/lsx/lsx-mov-1.c: New test.
