of a function has a resolved exception specification, then all declarations of
the function do.
We should probably improve the AST representation to make this implicit (perhaps
only store the exception specification on the canonical declaration), but this
fixes things for now.
The testcase for this (which used to assert) also exposes the actual bug I was
trying to reduce here: we sometimes fail to emit the body of an imported
special member function definition. Fix for that to follow.

specialization from a module. (This can also happen for function template
specializations in PCHs if they're instantiated eagerly, because they're
constexpr or have a deduced return type.)
