fix constant folding from array CTORs
This fixes the case where we try to fold a read from an
array initalizer and happen to cross the boundary of
multiple CTORs which isn't really supported. For the
interesting cases like the testcase we actually handle
the folding by encoding the whole initializer.

* gimple-fold.c (fold_array_ctor_reference): Do not
recurse to folding a CTOR that does not fully cover the
asked for object.
* gcc.dg/torture/pr96133.c: New testcase.
