	PR c++/34178
	PR c++/34340
	* repo.c (repo_emit_p): Return 2 for DECL_INTEGRAL_CONSTANT_VAR_P
	in class scope rather than DECL_INITIALIZED_BY_CONSTANT_EXPRESSION_P.
	Return 2 also if DECL_EXPLICIT_INSTANTIATION.
	* decl2.c (import_export_decl): Don't make VAR_DECLs import_p when
	flag_use_repository and repo_emit_p returned 2.

	* g++.dg/template/repo6.C: New test.
	* g++.dg/template/repo7.C: New test.
	* g++.dg/template/repo8.C: New test.
