This patch works around the problems with Ada's setting of
TYPE_MIN_VALUE/TYPE_MAX_VALUE and allows Ada to bootstrap.
I still think Ada is abusing our type system, but I'm in
no position to fix the Ada front-end.

There's still some problems in the acats testsuite that I
suspect are related to the VRP improvements.  I'll be looking
at those next.

This patch bootstraps and has been regression tested.  Again,
there are Ada testsuite failures related to the VRP improvements
which are neither fixed nor made worse by this patch.  I'm
going to suggest we keep this PR open for now.
