RISC-V: Rename rounding const fp function for refactor

The rounding related API shared one const, rename it to avoid
unnecessary redundant code.

gcc/ChangeLog:

	* config/riscv/riscv-v.cc (gen_ceil_const_fp): Remove.
	(get_fp_rounding_coefficient): Rename.
	(gen_floor_const_fp): Remove.
	(expand_vec_ceil): Take renamed func.
	(expand_vec_floor): Ditto.
