GDC and Codecov

[Iain Buclaw via D.gnu]

Hi,

Mini-project for anyone wanting to contribute but doesn't want to 
deal with C/C++.

Way back in June/July[1], I started looking at preliminarily at 
codecov for continuous coverage as well as the semaphore platform 
we use for builds[1].  After geting a fix in [2] that allows only 
scanning the parts of GCC that relate to the D frontend, it is 
usable as-is, as per the small test I did when I had a look.

All that's needed is to tie the two platforms together. I guess 
it should be:

1. Create a parallel job in semaphore CI to build GDC with gcov 
turned on, optimizations off.
2. Decide if we should run testsuite, or unittests, or both.
3. Upload to codecov
4. Update README with new badge of honour.

codecov two months later.
