RISC-V: Add sub-extension XTheadZvamo for T-Head VECTOR 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 sub-extension "XTheadZvamo" for the
"XTheadVector" extension, and it provides AMO instructions
for T-Head VECTOR vendor extension. The 'th' prefix and the
"XTheadVector" extension are documented in a PR for the
RISC-V toolchain conventions ([1]).
