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

+GCC supports vector intrinsics as specified in version 0.11 of the RISC-V
+vector intrinsic specification, which is available at the following link:
+@uref{https://github.com/riscv-non-isa/rvv-intrinsic-doc/tree/v0.11.x}.
+All of these functions are declared in the include file @file{riscv_vector.h}.
