[PATCH] D45454: Add llvm_gcov_flush to be called outside a shared library

[Marco Castelluccio via cfe-commits]

OK! Sounds good to me to keep it hidden until
https://reviews.llvm.org/D48538 is done (I'm going to try to finish it

GCC libgcov's implementation is more elaborate -- it allows gcov_flush to dump gcda data for all dynamic objects while making sure gcov_exit only dumps the gcda files from the same dynamic module (otherwise, there will be wrong profile merging). This is done via two levels of linked list.
