For Info, the last time this was proposed was in 2020:
https://reviews.llvm.org/D79521 - at that time, no vendor extensions had been
accepted upstream, and there was not yet a policy for upstream supporting
vendor extensions.

They match the existing names documented in
https://starfivetech.com/uploads/sifive-interrupt-cookbook-v1p2.pdf - we could
check them in clang case-insensitively, though.
