Zhongxing Xu 82003da8d3 Core analysis engine template cleanup step 2: 
merge GRCoreEngineImpl and GRCoreEngine.

Introduce a new interface class GRSubEngine as the subengine of GRCoreEngine.
GRExprEngine subclasses GRSubEngine now.

Dan Gohman 130e2c7aed Fix a bug in x86's PreprocessForRMW logic that was exposed 
by aggressive chain operand optimization. UpdateNodeOperands
does not modify the node in place if it would result in
a node identical to an existing node.

Dan Gohman 5758e1e92a Fix a few places in DAGCombiner that were creating all-ones-bits 
and high-bits values in ways that weren't correct for integer
types wider than 64 bits. This fixes a miscompile in
PPMacroExpansion.cpp in clang on x86-64.

Douglas Gregor 71dc50915a Implement transformation of template names within the generic tree 
transform, then use the result for template instantiation. The generic
transformation fixes a few issues:

  - It copes better with template template parameters and member
  templates (when they're implemented). 
  - The logic used to replace template template parameters with their
  arguments is now centralized in TransformDecl, so that it will apply
  for other declaration-instantiation steps.
  - The error-recovery strategy is normalized now, so that any error
  results in a NULL TemplateName.

Douglas Gregor 1135c35c7c Implement transformation of nested-name-specifiers within the general

transformation rather than implementing its own transformation.

Zhongxing Xu 20227f71d7 As GRState seems general enough, it is time to merge some template classes 
and their impl base classes. This can greatly simply some code of the core 
analysis engine. This patch merges ExplodedNodeImpl into ExplodedNode.

Ted Kremenek fa41714d8d Implement lazy "copying" of structures and arrays in RegionStore. While 
RegionStore already lazily abstracted the contents of arrays and structs, when
doing an assignment from one array/struct to another we did an explicit
element-wise copy, which resulted in a loss of laziness and huge performance
problem when analyzing many code bases.

Now RegionStoreManager handles such assignments using a new SVal could
'LazyCompoundSVal', which basically means the value of a given struct or array
(a MemRegion*) in a specific state (GRState). When we do a load from a field
whose encompassing struct binds to a LazyCompoundSVal, we essentially do a field
lookup in the original structure. This means we have essentially zero copying of
data for structs/arrays and everything stays lazy.

John McCall 9de556c8b6 AlisdairM pointed out that this will likely be relaxed in C++0x, so let's 
make a note of it in the test case.

Bob Wilson 488db94e7b Neon does not actually have VLD{234}.64 instructions. 
These operations will have to be synthesized from other instructions.

Bob Wilson e148ceaf65 Add a new pre-allocation pass to assign adjacent registers for Neon instructions 
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.
