RISC-V: Add vector fmin/fmax expanders.
This patch adds expanders for fmin and fmax. As per RISC-V V Spec 1.0
vfmin/vfmax are IEEE 754-2019 compliant which differs from IEEE 754-2008
that fmin/fmax require (particularly in the signaling-NaN handling).
Therefore the pattern conditions include a !HONOR_SNANS.
gcc/ChangeLog:
* config/riscv/autovec.md (<ieee_fmaxmin_op><mode>3): fmax/fmin
expanders.
(cond_<ieee_fmaxmin_op><mode>): Ditto.
(cond_len_<ieee_fmaxmin_op><mode>): Ditto.
(reduc_fmax_scal_<mode>): Ditto.
(reduc_fmin_scal_<mode>): Ditto.
* config/riscv/riscv-v.cc (needs_fp_rounding): Add fmin/fmax.
* config/riscv/vector-iterators.md (fmin): New UNSPEC.
(UNSPEC_VFMIN): Ditto.
* config/riscv/vector.md (@pred_<ieee_fmaxmin_op><mode>): Add
UNSPEC insn patterns.
(@pred_<ieee_fmaxmin_op><mode>_scalar): Ditto.
