RISC-V: Add T-Head FMemIdx vendor extension
T-Head has a range of vendor-specific instructions. Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the XTheadFMemIdx extension, a collection of T-Head-specific floating-point memory access instructions. The 'th' prefix and the "XTheadFMemIdx" extension are documented in a PR for the RISC-V toolchain conventions ([1]).
