turn unchecked type patterns into checked ones
the pattern `(_: T)` is made checkable using (ct: ClassTag[T]).unapply
by rewriting it to `ct(_: T)` (if there's a ClassTag[T] available)
similarly for extractors: if the formal type of the unapply method
is an uncheckable type, wrap in the corresponding classtag extractor (if available)
don't trigger rewrite on non-toplevel unchecked types
(i.e., only look at type constructor part of T when looking for unchecked types)
TODO: find outer match to figure out if we're supposed to be unchecked
would like to give users a chance to opt-out from the wrapping,
but finding the match to which this pattern belongs turned out to be tricky...
