Michael Starzinger 4902e91a82 [wasm] Fix reference type global initialization by index. 
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.
