RISC-V: Support FP MAX/MIN autovec for VLS mode

This patch would like to allow the VLS mode autovec for the
floating-point binary operation MAX/MIN.

Given below code example:

test (float *out, float *in1, float *in2)
{
  for (int i = 0; i < 128; i++)
    out[i] = in1[i] > in2[i] ? in1[i] : in2[i];
    // Or out[i] = fmax (in1[i], in2[i]);
}

Before this patch:
test:
  csrr    a4,vlenb
  slli    a4,a4,1
  li      a5,128
  bleu    a5,a4,.L2
  mv      a5,a4
.L2:
  vsetvli zero,a5,e32,m8,ta,ma
  vle32.v v16,0(a1)
  vle32.v v8,0(a2)
  vsetvli a3,zero,e32,m8,ta,ma
  vmfgt.vv        v0,v16,v8
  vmerge.vvm      v8,v8,v16,v0
  vsetvli zero,a5,e32,m8,ta,ma
  vse32.v v8,0(a0)
  ret

After this patch:
test:
  li      a5,128
  vsetvli zero,a5,e32,m1,ta,ma
  vle32.v v1,0(a1)
  vle32.v v2,0(a2)
  vfmax.vv        v1,v1,v2
  vse32.v v1,0(a0)
  ret

This MAX/MIN autovec acts on function call like fmaxf/fmax in math.h
too. And it depends on the option -ffast-math.

gcc/ChangeLog:

	* config/riscv/autovec-vls.md (<optab><mode>3): New pattern for
	fmax/fmin
	* config/riscv/vector.md: Add VLS modes to vfmax/vfmin.
