    debug/94273 - avoid creating type DIEs for DINFO_LEVEL_TERSE
    
    This avoids completing types for DINFO_LEVEL_TERSE by using
    the should_emit_struct_debug machinery.

            * dwarf2out.c (should_emit_struct_debug): Return false for
            DINFO_LEVEL_TERSE.
    
            * g++.dg/debug/pr94273.C: New testcase.
