That's essentially what -fprofile-arcs does --- except that is does so
not for every line of code, but only for every "basic block".  Your
problem, I think, is that the calls to static constructors/destructor
are not set up by the C++ compiler, but by the linker and some magic
clue from the runtime system, neither of which know about
-fprofile-arcs.
