- Remove calls to copyKillDeadInfo which is an N^2 function. Instead, propagate kill / dead markers as new instructions are constructed in foldMemoryOperand, convertToThressAddress, etc.
- Also remove LiveVariables::instructionChanged, etc. Replace all calls with cheaper calls which update VarInfo kill list.

-Set "Named Casts" feature to partial parser/sema support because reinterpret_cast is not properly implemented.
-Removed "Virtual functions" feature because it is already covered by "Class definitions".
-Removed "Templates" because we should either list *all* missing/supported features or just list the features with some support. Mentioning just a few missing features without listing all of them makes little sense.

-Add a link to cxx_status.html from get_involved.html/"Open Projects".

Have BugReporter::getCFG and BugReporter::getLiveVariables returns pointers instead of references, because they can both fail
on functions we cannot construct full CFGs for yet.

- 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.
