1) does it require them to be complete at the function definition? (it should)
2) Checking the eh specs on every call will slow the compiler down.
Is there a spare bit 'DECL_EH_MAY_CONTAIN_INCOMPLETE', perhaps it
could be placed in the eh list. Then you'd only need to check when there
had been an incomplete during construction.
