[PATCH] D51974: [GCOV] Remove useless loop when emiting edge counters

It seems that a Module can have several Compilation Units: a gcno and a gcda are generated for each of them.

But we don't need to generate same counters stuff for each CU.

All the tests in llvm/test, clang/test & compiler_rt/test/profile are ok.
