Fix MSAN failure on Function destruction
Summary:
When Function is destroyed, GlobalValue base class is destroyed, then
Value destructor would call use_empty, which ultimately attempts to
downcast 'this' to GlobalValue. This is UB, and is caught my MSAN as
accessing uninitialized memory.
Call materialized_use_empty, which doesn't call
assertModuleIsMaterializedImpl().
