[RISC-V] Drop unused parameters to restore bootstrap

Bootstraps on RISC-V recently started failing due to an unused parameter.  I've
only lightly tested this, but it should restore bootstrapping.  Pushing to the
trunk.

gcc/
	* config/riscv/riscv-v.cc (expand_const_vector_stepped): Drop unused
	SRC parameter. All callers changed.
	(expand_const_vector_interleaved_stepped_npatterns): Likewise.
	(expand_const_vector): Corresponding changes.
