r332720 - Move #include manipulation code to new lib/Tooling/Inclusions.

[David Blaikie via cfe-commits]

I haven't looked in detail here, but in general: Don't split an
implementation and its headers into different notional libraries, as that
breaks modular code generation (an implementation and its headers usually
have circular dependencies - inline functions that call non-inline
functions, and the other way around & so if they're in two different
libraries they won't be able to link (due to the way unix linkers
work/dependencies are resolved in a single pass, never looping back around).
