This fixes initialization of reference type global variables (i.e.
anyref and except_ref) based on an index of another global. It extends
the existing support to exception types, fixes the logic, and also fixes
a missing write barrier.

This extends the support for the "except_ref" type on global variables
to support mutable globals, as well as importing and exporting such
globals. Test coverage is also increased.

This adds basic support and tests for having global variables of type
"except_ref" that are default initialized to "null". The functionality
is part of the exception handling proposal and solely enabled by the
corresponding feature flag.
