Make __gcov_flush flush counters for all shared libraries
Summary:
This will make the behavior of __gcov_flush match the GCC behavior.
I would like to rename __gcov_flush to __llvm_gcov_flush (in case of programs linking to libraries built with different compilers), but I guess we can't for compatibility reasons.
