[PATCH] Docs: Add doc for RISC-V vector intrinsics

[Kito Cheng]

Document which version of RISC-V vector intrinsics has implemented in
GCC.

gcc/ChangeLog:

	* doc/extend.texi (Target Builtins): Add RISC-V Vector
	Intrinsics.
	(RISC-V Vector Intrinsics): Document GCC implemented which
	version of RISC-V vector intrinsics and its reference.

OK for 13?
