c++/modules: Ensure vtables are emitted when needed [PR120349]
I missed a testcase in r16-688-gc875748cdc468e for whether a GM vtable
should be emitted in an importer when it has no non-inline key function.
Before that patch the code worked because always we marked all vtables
as DECL_EXTERNAL, which then meant that reading the definition marked
them as DECL_NOT_REALLY_EXTERN.
This patch restores the old behaviour so that vtables are marked
DECL_EXTERNAL (and hence DECL_NOT_REALLY_EXTERN).
PR c++/120349
gcc/cp/ChangeLog:
* module.cc (trees_out::core_bools): Always mark vtables as
DECL_EXTERNAL.
gcc/testsuite/ChangeLog:
* g++.dg/modules/vtt-3_a.C: New test.
* g++.dg/modules/vtt-3_b.C: New test.
