[cfe-commits] MS constructor / destructor improvements

[João Matos]

>From what I understood, MSVC emits a "scalar deleting" and "vector
deleting" destructors, while also mentioning a "vbase destructor". I'm
not so sure this patch is 100% correct, but it is definitely a
work-in-progress. I tried to map them as accurately as possible, but
more research needs to be done to test in MSVC and check how it works
in each case.

I intend to keep working on it, after we also merge some of the code
by r4start. This patch helps in the meantime, and fixes a big bug
since Clang generates the same mangling while generating the
constructors / dtors and asserts. See
http://llvm.org/bugs/show_bug.cgi?id=12784

The patch allow those cases to start working.
