Subject: [PATCH] Limit the clang AST crash workaround to clang 7.0

The workaround disables some functionality when building with clang in
order to work around a clang bug that was introduced in 7.0 and fixed in
8.0.
Limit the workaround to clang versions actually affected by the bug.

Verified to work perfectly when built with clang 14.0.3.
