These are somewhat special in that they wrap any other FrontendAction,
running various ARC transformations or checks prior to the standard
action's run. To implement them easily, this extends FrontendAction to
have a WrapperFrontendAction utility class which forwards all calls by
default to an inner action setup at construction time. This is then
subclassed to override the specific behavior needed by the different
ARCMT tools.
Finally, FrontendTool is taught how to create these wrapper actions from
the existing flags and options structures.
The result is that clangFrontend no longer depends on clangARCMigrate.
This is very important, as clangARCMigrate *heavily* depends on
clangFrontend. Fundamentally ARCMigrate is at the same layer as
a library like Rewrite, sitting firmly on top of the Frontend, but tied
together with the FrontendTool when building the clang binary itself.

too low-level to actually be useful but is just interesting enough for
people to try to use it (which won't actually work beyond toy examples).
To bring back the AST printer, it needs to be:
- Complete, covering all of C/C++/Objective-C
- Documented, with appropriate Schema against which we can validate
the output
- Designed for C/C++/Objective-C, not Clang's specific ASTs
- Stable across Clang versions
- Well-tested

callbacks class.
- Aside from being generally cleaner, this also allows -H to work correctly in
modes other than standard preprocessing (e.g., -c, -MM, etc.)

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.

Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen. This is suboptimal for
clients which only wish to make use of the frontend. CodeGen in
particular introduces a large number of unwanted dependencies.
This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries. The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).
After applying this patch, Clang builds correctly using CMake and
shared libraries ("cmake -DBUILD_SHARED_LIBS=ON").
N.B. This patch includes file renames which are indicated in the
patch body.
Changes in this revision of the patch:
- Fixed some copy-paste mistakes in the header files
- Modified certain aspects of the coding to comply with the LLVM
Coding Standards

The macros required for DeclNodes use have changed to match the use of
StmtNodes. The FooFirst enumerator constants have been named firstFoo
to match usage elsewhere.

- This reimplements -verify as just another DiagnosticClient, which buffers the diagnostics and checks them when the source file is complete. There are some hacks to make this work, but they are all internal, and this exposes a better external interface.
- This also tweaks a few things:
o Errors are now just regular diagnostics.
o Frontend diagnostics are now caught (for example, errors in command line arguments), although there isn't yet a way to specify that they are expected. That would be nice though.
- Not yet used.

Decl* is the declaration associated with this source location and Stmt* is the statement/expression that the location points to.
If the location does not point to a statement node, Stmt* is null.
ResolveLocationInAST (along with converting a file:line:column triplet to a SourceLocation) will be useful for an IDE client and for clang's test suite.
