the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.
This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator. We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

This does not yet add the profile_rt library to the link step if -fprofile-arcs
is enabled when linking.

Rename the 'EntoSA' directories to 'StaticAnalyzer'.
Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).

r110903 introduced a dependency from Frontend to every library that
declared an Action by introducing Action references that previously
resided in the driver in the file ExecuteCompilerInvocation.cpp.
This patch moves ExecuteCompilerInvocation to a new library named
FrontendTool which is intended to bear these dependencies.

and 'llvm-dis' is:
$ clang -cc1 -emit-llvm FOO.bc -o -
and 'opt' is, e.g.:
$ clang -cc1 -emit-llvm -O3 -o FOO.opt.ll FOO.ll
and 'llc' is, e.g.:
$ clang -cc1 -S -o - FOO.ll
The nice thing about using the backend tools this way is that they are guaranteed to exactly match how the compiler generates code (for example, setting the same backend options).

(1) libAnalysis is a generic analysis library that can be used by
Sema. It defines the CFG, basic dataflow analysis primitives, and
inexpensive flow-sensitive analyses (e.g. LiveVariables).
(2) libChecker contains the guts of the static analyzer, incuding the
path-sensitive analysis engine and domain-specific checks.
Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.
This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker. More changes pending. :)
This change also exposed a layering violation between AnalysisContext
and MemRegion. BlockInvocationContext shouldn't explicitly know about
BlockDataRegions. For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet). We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.

diagnostics. This builds on the patch that Sebastian committed and
then revert. Major differences are:
- We don't remove or use the current ".def" files. Instead, for now,
we just make sure that we're building the ".inc" files.
- Fixed CMake makefiles to run TableGen and build the ".inc" files
when needed. Tested with both the Xcode and Makefile generators
provided by CMake, so it should be solid.
- Fixed normal makefiles to handle out-of-source builds that involve
the ".inc" files.
I'll send a separate patch to the list with Sebastian's changes that
eliminate the use of the .def files.

- Add Options.def file, collects option information.
- Actual option instantiation is handled lazily by OptTable to allow
the driver to not need to instantiate all options.
- cast<> support for Option, other minor tweaks.
