Add whereFrom and whereFrom# primop
The `whereFrom` function provides a Haskell interface for using the
information created by `-finfo-table-map`. Given a Haskell value, the
info table address will be passed to the `lookupIPE` function in order
to attempt to find the source location information for that particular closure.
At the moment it's not possible to distinguish the absense of the map
and a failed lookup.
