[AArch64] Add support for SVE F{MAX,MIN}NM immediate
This patch uses the immediate forms of FMAXNM and FMINNM for
unconditional arithmetic.
The same rules apply to FMAX and FMIN, but we only generate those
via the ACLE.

* config/aarch64/predicates.md (aarch64_sve_float_maxmin_immediate)
(aarch64_sve_float_maxmin_operand): New predicates.
* config/aarch64/constraints.md (vsB): New constraint.
(vsM): Fix typo.
* config/aarch64/iterators.md (sve_pred_fp_rhs2_operand): Use
aarch64_sve_float_maxmin_operand for UNSPEC_COND_FMAXNM and
UNSPEC_COND_FMINNM.

Use aarch64_sve_float_maxmin_operand for operand 2.
(*<SVE_COND_FP_MAXMIN_PUBLIC:optab><SVE_F:mode>3): Likewise.
Add alternatives for the constant forms.
