serialization logic as well as driver code is now in
Driver/SerializationTest.cpp.  The status of this code is that it
should be used by no clients.

Added --test-pickling option to driver to run the serialization code.

Modified IdentifierInfo and IdentifierTable to have friend classes
that permit object serialization.  Such friendship may not be needed
in the final design.

@selector probably gets this wrong also.

Rename SourceRange::Begin()/End() to getBegin()/getEnd() for

$ clang rewrite.c -rewrite-test
prints:

int foo() {
        b:      foo();
f:      foo();
    foo();
}

for:

int foo() {
	b:	foo();
f:	foo();
    foo();
}

amazing.

Fix a latent bug in MinimalActions (created by a recent name change).

predefined macros.  Previously, these were handled by the driver,
now they are handled by the preprocessor.

Some fallout of this:

1. Instead of preprocessing two buffers (the predefines, then the 
   main source file)  we now start preprocessing the main source 
   file and inject the predefines as a "psuedo #include" from the
   main source file.
2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify
   Preprocessor::isInPrimaryFile.
3. The driver doesn't have to know about standard #defines, the
   preprocessor knows, which is nice for people wanting to define
   their own drivers.
4. This allows us to put normal tokens in the predefine buffer,
   for example a definition for __builtin_va_list that is 
   target-specific, and a typedef for id in objc.

using "-parse-ast -verify".

Updated all test cases (using a sed script) that invoked -parse-ast-check to
now use -parse-ast -verify.

Fixed a bug where using "-verify" instead of "-parse-ast-check" would not
correctly create the DiagClient needed to accumulate diagnostics.

ASTConsumer can also be verified using the diagnostics checker.  From
the command line, users may activate diagnostic checking using the
"-verify" option.  For example, "clang -verify -warn-dead-stores"
checks if the warnings flagged by the dead store checker match those
in the comments.

Note that we still have the option "-parse-ast-check" for backwards
comptability with existing test cases.  This option is now equivalent to 
"-parse-ast -verify".

"CheckDiagnostics" (used for -parse-ast-check) to check the
diagnostics of any ASTConsumer.

Reimplemented CheckDiagnostics to use CheckASTConsumer instead.

Added driver option -warn-dead-stores-check, which checks the
diagnostics generated by the DeadStores checker.  This is implemented
using CheckASTConsumer.111

between forward and backward analyses, with trait classes being used
to implement the key differences in operations/functionality.

Converted the LiveVariables analysis to use the generic DataflowSolver.  This,
along with removing some extra functionality that was not needed, reduced
the code for LiveVariables by over half.

Modified Driver code to handle the updated interface to LiveVariables.

Modified the DeadStores checker to handle the update interface to
LiveVariables.

Updated DataflowValues (generic ADT to store dataflow values) to also
store values for blocks.  This is used by DeadStores.  Updated some comments.
