[LLVMdev] "has different visibility" warnings

[Daniel Dunbar]

The root of the problem is that I committed the changes to apply
-fvisibility-lines-hidden
but that was later backed out. If you have object files built in the
time in between the
commit and the backing out then they will differ. A clean rebuild
should get rid of the
warnings.
