RISC-V: Handle FP NE operator via inversion in cond-operation expansion

We have no FNE.fmt machine instructions, but we can emulate them for the
purpose of conditional-move and conditional-add operations by using the
respective FEQ.fmt instruction and then swapping the data input operands
or complementing the mask for the conditional addend respectively, so
update our handlers accordingly.

	gcc/
	* config/riscv/riscv-protos.h (riscv_expand_float_scc): Add
	`invert_ptr' parameter.
	* config/riscv/riscv.cc (riscv_emit_float_compare): Add NE
	inversion handling.
	(riscv_expand_float_scc): Pass `invert_ptr' through to
	`riscv_emit_float_compare'.
	(riscv_expand_conditional_move): Pass `&invert' to
	`riscv_expand_float_scc'.
	* config/riscv/riscv.md (add<mode>cc): Likewise.
