[cfe-dev] supress Clang deperecated header warning [gcc's -Wcpp]

[Nico Weber]

It looks like this is just a #warning, not a "real" deprecation warning
from looking at that source file.

clang prints "./test.h:7:3: warning: "deprecated" [-W#warnings]" for me,
and passing -Wno-#warnings makes it go away.
