After builtin macro expansion in `Preprocessor::ExpandBuiltinMacro` the result token may have the `Token::NeedsCleaning` flag set which causes an assertion failure later on when the lexer retrieves the spelling of the token in `getSpellingSlow`. This commit adds an `Tok.clearFlag(Token::NeedsCleaning)` call to the end of `ExpandBuiltinMacro`. Closes #128384
