LLVM 18 std lib updates and fixes

* some manual fixes to generated CPU features code. In the future it
  would be nice to make the script do those automatically.

* add to various target OS switches. Some of the values I was unsure of
  and added TODO panics, for example in the case of spirv CPU arch.
