[llvm-dev] [llvm-c] Deprecated functions

I think there's a two different "levels" of deprecated:
a) There's a better function you should know about and prefer in new code,
but the old one will (probably) not be removed. This sort of deprecation
should only be mentioned in comments, since there's no real reason to have
people's builds start spewing warning messages if they used the old
b) There's a better function, and the old one will be removed soon. These
ought to use a deprecated attribute, in order to entice people to switch
over before it turns into a "no such function" error.

I'd expect most of the deprecations in the C API to be of the former kind.
