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.

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

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  Looks like the x64 projects got out of date and this brings them up to code.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.

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

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.

with a huge "size" parameter is actually quite inefficient.

This makes sure that all new nodes are expunged, not
just those the top node of a new subtree.
