Reapply "[DebugInfo] Drop DBG_VALUE_LISTs with an excessive number of debug operands"
    
    Reapply b623df3c, which was reverted while reverting a different patch
    with a breaking change. There are no underlying issues with this patch,
    so no changes have been made to the original patch.
    
    This reverts commit b11e4c990771541e440861f017afea7b4ba162f4.
