Argyrios Kyrtzidis 1240f4e53a [arcmt] Remove '-arcmt-modify-in-memory', it turned out less useful than we hoped it would be.

Chandler Carruth b570351059 Raise the ARCMT functionality in Clang into proper FrontendActions.
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.

Ted Kremenek 4f76f4ae31 Re-enable disable free optimization where the FrontendAction is not freed when -disable-free is passed. This accidentally was commited in r128011.

Ted Kremenek 5e14d39a88 Improve crash recovery cleanup to recovery CompilerInstances during crash recovery. This was a huge resource "root" during crashes.
This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct
ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance
object.

Douglas Gregor cfee35b845 Remove the AST printer (-ast-print-xml), which is too incomplete and
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

Argyrios Kyrtzidis 17bee3e70a Intoduce '-analyzer-checker-help' flag which outputs a list of all available static analyzer checkers.
This is pretty basic for now, eventually checkers should be grouped according to package, hidden checkers should be indicated etc.

Douglas Gregor d6f8124c9c Eliminate the internal command-line option for viewing inheritance in C++ classes, since it's only really worked for the trivial cases anyway due to lame pseudo-parsing of the class name. The viewInheritance() function is still available for use in the debugger, where this is far more useful

Argyrios Kyrtzidis 556c45e9c5 [analyzer] Overhauling of the checker registration mechanism.
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.

Ted Kremenek f8cbac4b91 Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.
This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

Ted Kremenek d99bd55a5e Chris Lattner has strong opinions about directory
layout.  :)

Rename the 'EntoSA' directories to 'StaticAnalyzer'.

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

John McCall 9b66c4bbbe Add -cc1 -ast-dump-xml, an excessively detailed XML dump of the internals
of the ASTs.  Only available in assertions builds.  No stability guarantee.

This is intended solely as a debugging tool.  I'm not sure if the goals
are sufficiently aligned with the XML printer to allow a common
implementation.

Currently just falls back on the StmtDumper to display statements,
which means it doesn't produce valid XML in those cases.

Peter Collingbourne 85dd0bd18d Move ExecuteCompilerInvocation to a new library FrontendTool
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.
