It's important for GCOV to report coverage for functions that are
really present in a source file. Lambdas are such functions.
On the other hand functions like _Z41__static_initialization_and_destruction_*
or some implicit constructors (Centering<3>::Centering(Centering<3> const&))
should not be reported. It confuses a user. Note that both have a valid
location and one can't distinguish them.

That's why I would like to sort out lambdas from others.
