This was just a thinko. The API StackFrame::GetVariableList takes a bool for
"get_file_globals" which if true will also find file statics and file globals.
But we only were passing that as true if the ValueType was
eValueTypeVariableGlobal, which meant that we never find file statics. It's
okay if we cast too wide a net when we do GetVariableList as later on we check
against the ValueType to filter globals from statics.
There was a test that had a whole bunch of globals and tested FindValue on all
of them, but had no statics. So I just made one of the globals a file static,
which verifies the fix.
