The llvm_gcda_increment_indirect_counter function writes to the arguments that
are passed in. However, those arguments may be in a write-protected area, as far
as the runtime library is concerned. For instance, the data could be placed into
a 'linkedit' section, which isn't writable. Emit the code from
llvm_gcda_increment_indirect_counter directly into the function instead.
Note: The code for this is ugly, and can lead to bloat. We should look into
simplifying this code instead of having all of these branches.
