That means that a default-CC function type is different from a specifically-cdecl function type, but I can live with that.
So you're saying we should get rid of getCanonicalCallConv()? Then I can
dispense with the AST hook, too.

I don't know about this. The whole point of canonicalizing the CC was
that cdecl function types were compatible with default-CC function
types. This matters when, e.g., trying to merge two compatible
declarations, or assigning function pointers. Are you sure you can live
with it now?
