THRIFT-4399 fix plugin.thrift & assoc C++ code to respect unions
plugin.thrift defines t_const_value as a union. But in plugin_output.cc
and plugin.cc, the converters clearly either (a) SET NEITHER of
identifier_val & enum_val, or (b) SET BOTH. But these are two different
fields in the union. So clearly, the type t_const_value isn't being
treated as a union.
I think we need to fix Thrift's treatment of unions, but independently,
the plugin should use Thrift's type system in a correct manner. This is
easy-to-fix, but since the current plugin relies on a bug, the fix will
be a breaking change.
