Subject: [PATCH] RISC-V: Support MASK_LEN_{LOAD_LANES,STORE_LANES}

This patch allow us auto-vectorize this following case:

  void __attribute__ ((noinline, noclone))                                     \
  NAME##_8 (OUTTYPE *__restrict dest, INTYPE *__restrict src,                  \
	    MASKTYPE *__restrict cond, intptr_t n)                             \
  {                                                                            \
    for (intptr_t i = 0; i < n; ++i)                                           \
      if (cond[i])                                                             \
	dest[i] = (src[i * 8] + src[i * 8 + 1] + src[i * 8 + 2]                \
		   + src[i * 8 + 3] + src[i * 8 + 4] + src[i * 8 + 5]          \
		   + src[i * 8 + 6] + src[i * 8 + 7]);                         \
  }

  TEST_LOOP (NAME##_f32, OUTTYPE, INTYPE, int32_t)                               \

  TEST2 (NAME##_i32, OUTTYPE, int32_t)                                         \

  TEST1 (NAME##_i32, int32_t)                                                  \
