Bill Wendling e647659d58 Add a way to register and execute "writeout" functions. 
It may be prohibitively expensive to write out >1000 files at the same time. So
we would rather emit them serially. These functions allow the GCOV
implementation to register the functions that writeout the GCOV information per
compile unit. At exit, they are written.

Bill Wendling 2428f167f7 Add some GCOV functions that register all of the __llvm_gcov_flush() functions. 
The __llvm_gcov_flush() functions only work for the local compile unit. However,
when __gcov_flush() is called, the user expects all of the counters to be
flushed, not just the ones in the current compile unit.

This adds some library functions that register the flush functions. It also
defined __gcov_flush() so that loops through that list and calls the functions.
