fixes #23432
After #22029 generic parameter types no longer match
typedescparameters in overloading, as this previously instantiated procs with an unresolved type as atypedescvalue. However macros and templates don't use the same mechanism for generic instantiation, cannot delay their instantiations further than the point that they get compiled (i.e. are generically instantiated) and can inspect types more precisely anyway, so for practicality purposes we can whitelist them fortypedescand keep old code working.If whitelisting macros and templates isn't sufficient (i.e. in cases where
c.calleeSymis nil) we can also blacklist runtime routines (c.calleeSym != nil and c.calleeSym.kind in (routineKinds - {skMacro, skTemplate})).
