Finish "Adapt -fsanitize=function to SANITIZER_NON_UNIQUE_TYPEINFO"
i.e., recent 5745eccef54ddd3caca278d1d292a88b2281528b:
* Bump the function_type_mismatch handler version, as its signature has changed.
* The function_type_mismatch handler can return successfully now, so
SanitizerKind::Function must be AlwaysRecoverable (like for
SanitizerKind::Vptr).
* But the minimal runtime would still unconditionally treat a call to the
function_type_mismatch handler as failure, so disallow -fsanitize=function in
combination with -fsanitize-minimal-runtime (like it was already done for
-fsanitize=vptr).
* Add tests.
