gcov support unique-cause MC/DC. The first seems easier and I might try
implementing a prototype.
There is room for both, e.g. -fcondition-coverage={masking,unique} or similar.
I don't think supporting unique cause MC/DC would be too hard in GCC either,
using a method similar to GCC's upcoming path coverage and LLVM's MC/DC, if it
is desirable.
