LoongArch: Provide fmin/fmax RTL pattern for vectors
We already had smin/smax RTL pattern using vfmin/vfmax instructions.
But for smin/smax, it's unspecified what will happen if either operand
contains any NaN operands. So we would not vectorize the loop with
-fno-finite-math-only (the default for all optimization levels expect
-Ofast).
But, LoongArch vfmin/vfmax instruction is IEEE-754-2008 conformant so we
can also use them and vectorize the loop.
gcc/ChangeLog:
* config/loongarch/simd.md (fmax<mode>3): New define_insn.
(fmin<mode>3): Likewise.
(reduc_fmax_scal_<mode>3): New define_expand.
(reduc_fmin_scal_<mode>3): Likewise.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/vfmax-vfmin.c: New test.
