Anders Carlsson c778540f9a Add a ThunkAdjustment struct which holds a non-virtual and a virtual adjustment offset. Start using it. General cleanup in Mangle.cpp.

Ted Kremenek 0f5e6f8805 Enhance LiveVariables to understand that blocks can extend the liveness of a variable by "capturing" them in a BlockExpr.
This required two changes:

1) Added 'getReferencedgetReferencedBlockVars()' to AnalysisContext so
that clients can iterate over the "captured" variables in a block.

2) Modified LiveVariables to take an AnalysisContext& in its
constructor and to call getReferencedgetReferencedBlockVars() when it
processes a BlockExpr*.

Chris Lattner 7a5b56aca9 Change the other half of aliasGEP (which handles GEP differencing) to use DecomposeGEPExpression. This dramatically simplifies and shrinks the code by eliminating the horrible CheckGEPInstructions method, fixes a miscompilation (@test3) and makes the code more aggressive. In particular, we now handle the @test4 case, which is reduced from the SmallPtrSet constructor. Missing this caused us to emit a variable length memset instead of a fixed size one.

Chris Lattner 5341c9679d Generalize DecomposeGEPExpression to exactly handle what Value::getUnderlyingObject does (when TD is around). This allows us to avoid calling DecomposeGEPExpression unless the ultimate alias check we care about passes, speedup up BasicAA a bit.

Chris Lattner 8928899413 Implement a new DecomposeGEPExpression method, which decomposes a GEP into a list of scaled offsets. Use this to eliminate some previous ad-hoc code which was subtly broken (it assumed all Constant*'s were non-zero, but strange constant express could be zero).

Douglas Gregor ff790f15c4 Refactor our handling of expression evaluation contexts, so that Sema
maintains a stack of evaluation contexts rather than having the parser
do it. This change made it simpler to track in which contexts
temporaries were created, so that we could...

"Forget" about temporaries created within unevaluated contexts, so
that we don't build a CXXExprWithTemporaries and, therefore, destroy
the integral-constness of our expressions. Fixes PR5609.

Bob Wilson 2d4ff12da9 Split tail duplication into a separate pass. This is needed to avoid
running tail duplication when doing branch folding for if-conversion, and
we also want to be able to run tail duplication earlier to fix some
reg alloc problems.  Move the CanFallThrough function from BranchFolding
to MachineBasicBlock so that it can be shared by TailDuplication.

Ted Kremenek b63ad7a6c1 Refine MemRegions for blocks. Add a new region called
'BlockDataRegion' to distinguish between the code associated with a
block (which is represented by 'BlockTextRegion') and an instance of a
block, which includes both code and data.  'BlockDataRegion' has an
associated LocationContext, which can be used to eventually model the
lifetime of a block object once LocationContexts can represent scopes
(and iterations around a loop, etc.).

Douglas Gregor f73b282bf0 Implement the rules in C++ [basic.link] and C99 6.2.2 for computing
the linkage of a declaration. Switch the lame (and completely wrong)
NamedDecl::hasLinkage() over to using the new NamedDecl::getLinkage(),
along with the "can this declaration be a template argument?" check
that started all of this.

Fixes -fsyntax-only for PR5597.

Ted Kremenek acdc817ed9 When dispatching to Checker objects in GRExprEngine::CheckerVisit(),
only stop processing the checkers after all the nodes for a current
check have been processed.  This (I believe) handles the case where
PredSet (the input nodes) contains more than one node due to state
bifurcation.  Zhongxing: can you review this?

Douglas Gregor ed5731f68a Diagnose ill-formed uses of default template arguments in
function templates (in C++98), friend function templates, and
out-of-line definitions of members of class templates.

Also handles merging of default template arguments from previous
declarations of function templates, for C++0x. However, we don't yet
make use of those default template arguments.

Bob Wilson 120f729eca Based on the testcase for pr3120, running on my MacPro with Xeon processors,
it is definitely profitable to tail duplicate indirect branches for x86.
This is likely to be true to various degrees for all modern x86 processors.
