[clang] nonblocking/nonallocating attributes (was: nolock/noalloc) (PR #84983)

[via cfe-commits]

Overall, it’s looking pretty good I’d say; there are some minor things here and there, but nothing major.

Missing are also more tests that involve dependent expressions, especially tests that actually instantiate such templates.
