and now we require a FunctionDecl* object so that we can also keep track of
all of the ParmDecls.
Modified clients of LiveVariables to conform to the new interface.

values for the block-level expressions.
Modified 'LiveVariables' to provide the option to clients to record
liveness information for block-level expressions (using the above feature).
Modified 'DeadStores' to conform to the new interface of 'LiveVariables'.
Modified 'GRConstants' to compute liveness information for block-level
expressions.

Created include/clang/Analysis/Analyses directory.
- Moved LiveVariables.h and UninitializedValues.h into this dir.
Moved ExprDeclBitVector.h into Analysis/Support.
Updated all clients who use these headers to reflect the new paths.

Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:
FullLoc.getManager().someMethod(FullLoc.getLocation());
instead we have:
FullLoc.someMethod();
Modified TextDiagnostics (and related classes) to use this short-hand.

SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.
Modified all users of Diagnostics to comply with this new interface.
Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).
Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

Rename SourceRange::Begin()/End() to getBegin()/getEnd() for
consistency with other code.
Start building the rewriter towards handling @encode.

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.

if the assigned value is a constant expression, e.g.:
int x = 0;
We then check to see if "x" is ever reassigned later. If so, we don't
emit a warning. This is because programmers frequently use defensive
programming to make sure a variable has a defined value.

that refer to direct function calls.
Modified interface of LiveVariables to only track liveness of VarDecls.
This cleans up a bunch of edge cases, and removed the bug just mentioned.

but never used.
Fix a bug in LiveVariables where uses on the LHS of self-assign
operators (e.g +=, *=, etc) would not be properly recorded in the
liveness state of the variable.
