- Add LiveVariables::replaceKillInstruction. This does a subset of instructionChanged. That is, it only update the VarInfo.kills if the new instruction is known to have the correct dead and kill markers.
- CommuteInstruction copies kill / dead markers over to new instruction. So use replaceKillInstruction instead.

Make LiveVariables even more optional, by making it optional in the call to TargetInstrInfo::convertToThreeAddressInstruction
Also, if LV isn't around, then TwoAddr doesn't need to be updating flags, since they won't have been set in the first place.

SelectionDAG::SelectNodeTo in the instruction selector. This
updates existing nodes in place instead of creating new ones.

Go back to selecting ISD::DBG_LABEL nodes into
TargetInstrInfo::DBG_LABEL nodes instead of leaving them
unselected, now that SelectNodeTo allows us to update them
in place.

Update test case:  simply running "clang -checker-simple" doesn't invoke the dead store checker anymore.  We need "-warn-dead-stores" as well.

ccc-analyzer now dispatches the options "-checker-cfref" and "-warn-dead-stores" to clang instead of just "-checker-cfref".

TwoAddressInstructionPass doesn't really require LiveVariables, it just needs to update it if it's already around.

Refactored some of the BugReporter interface so that data such as the ASTContext&, PathDiagnosticClient*, can be provided by an external source.
Split BugReporter into BugReporter and GRBugReporter so checkers not based on GRExprEngine can still use the BugReporter mechanism.

VStudio x64 build fixes.  Looks like the x64 projects got out of date and this brings them up to code.  I've built the project with these new vcproj files for win32 and x64 both debug and release.

This allows an optimization in AnalysisConsumer where the same LiveVariables information is used between multiple analyses.

llvm-svn: 53046

for instance.

Also, move large sets and vectors out of instance variables and onto the stack,
and give them more reasonable sizes.

llvm-svn: 53044

Modified the DeadStores logic in AnalysisConsumer.cpp to use the LiveVariables object created by the AnalysisManager.

llvm-svn: 53043

Added method "HandleTranslationUnit" to ASTConsumer.  This is called by ParseAST when all of the ASTs in a translation unit have been built.

Renamed -dump-cfg to -cfg-dump, and -view-cfg to -cfg-view.  This naming better matches the same options for asts (e.g. -ast-dump).

to be passed the list of value types, and use this
where appropriate.  Inappropriate places are where
the value type list is already known and may be
long, in which case the existing method is more
efficient.
