RISC-V: Add autovec FP binary operations.
This implements the floating-point autovec expanders for binary
operations: vfadd, vfsub, vfdiv, vfmul, vfmax, vfmin and adds
tests.
The existing tests are split up into non-_Float16 and _Float16
flavors as we cannot rely on the zvfh extension being present.
As long as we do not have full middle-end support we need
-ffast-math for the tests.
In order to allow proper _Float16 this patch disables
general _Float16 promotion to float TARGET_ZVFH is defined
similar to TARGET_ZFH or TARGET_ZHINX.

expander.

(enum fixed_point_rounding_mode): ...to this.
(enum frm_field_enum): Rename this...
(enum floating_point_rounding_mode): ...to this.
* config/riscv/riscv-v.cc (emit_vlmax_fp_insn): New function
* config/riscv/riscv.cc (riscv_const_insns): Clarify const
vector handling.
(riscv_libgcc_floating_mode_supported_p): Adjust comment.
(riscv_excess_precision): Do not convert to float for ZVFH.
