RISC-V: Use VLS modes if the NITERS is known and smaller than VLS mode elements.

void
foo8 (int64_t *restrict a)
{
  for (int i = 0; i < 16; ++i)
    a[i] = a[i]-16;
}

We use VLS modes instead of VLA modes even it is specified by dynamic LMUL.

gcc/ChangeLog:

	* config/riscv/riscv-vector-costs.cc (costs::preferred_new_lmul_p): Use VLS modes.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/costmodel/riscv/rvv/no-dynamic-lmul-1.c: New test.
