Use the SymbolTable::isEmpty() method instead of checking for no value

planes. A SymbolTable could still have types in it! This fixes problems
with two regression tests that failed because a symbol table that only
contained types was being omitted from bytecode files. Thanks to Chris
for the reduced test case that helped find this immediately.
