Log:
Fix a bad consequence of the new story for the generic toT/fromT functions
derived from data types declarations. The problem was that they were being
generated and then discarded by the simplifier, because there was nothing
keeping them alive.
This commit
* Adds a field tcg_keep to the TcGblEnv, which records things
to be kept alive;
* Makes the desugarer pin the keep-alive flag on each binding
(it's actually a call to setIdLocalExported)
* Removes that job from updateBinders in SimplCore
It's somewhat tiresome, but not really difficult.
