[clang] [clang][bytecode][NFC] Check for custom typechecking in call cleanup (PR #106826)

[Timm Baeder via cfe-commits]

The comment already explains that this is only true for _some_ builtin functions. This also brings the time it takes me to run the builtin-functions.cpp test locally from 50s down to 47s.
