The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.
Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.
Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.

a nice shiny B+ Tree variant. This fixes the last of the known algorithmic
issues with the rewriter, allowing a significant speedup. For example,
-emit-html on Ted's 500K .i file speeds up from 26.8s -> 0.64s in a
debug build (41x!) and 5.475s -> 0.132s (41x!) in an optimized build.
This code is functional but needs to be cleaned up, ifdefs removed, better
commented, and moved to a .cpp file. I plan to do this tomorrow.

This results in an (IMO) simpler algorithm, results in fewer splits, and
is more amenable to delta handling (there is no reason to mutate the tree
at all when adding a delta to a position that already exists in the tree).
