No.  We tried, gave up, CC'ed ourselves on bugs, and filed some new ones.  See:

<http://llvm.org/bugs/show_bug.cgi?id=11760>
<http://llvm.org/bugs/show_bug.cgi?id=11457>
<http://llvm.org/bugs/show_bug.cgi?id=11809>

AFAICT, the llvm community is not too bothered about code coverage features.  :(

I'd suggest doing coverage with linux+gcc.

Cheers,
