RISC-V: Add sifive_vector.h

sifive_vector.h is a vendor specfic header, it should include before
using sifive vector intrinsic, it's just include riscv_vector.h for now,
we will separate the implementation by adding new pragma in future.

gcc/ChangeLog:

	* config.gcc (riscv*): Install sifive_vector.h.
	* config/riscv/sifive_vector.h: New.
