[RISCV][Clang] Add some RVV Floating-Point intrinsic functions.

Support the following instructions which have the same class. 1. Vector Single-Width Floating-Point Subtract Instructions 2. Vector Single-Width Floating-Point Multiply/Divide Instructions 3. Vector Floating-Point MIN/MAX Instructions 4. Vector Floating-Point Sign-Injection Instructions Reviewed By: craig.topper Authored-by: Roger Ferrer Ibanez <rofirrim@gmail.com> Co-Authored-by: Zakk Chen <zakk.chen@sifive.com> Differential Revision: https://reviews.llvm.org/D99668
