Evan Cheng 9f8b66f3f1 Use std::replace instead of std::find and push_back.

Devang Patel 7dcfff392a Undo previous patch. It is not that simple to fix dom info here.

Evan Cheng 7a265d83bf - 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.

Evan Cheng c939f45fe7 commuteInstruction should preserve dead markers.

Owen Anderson 30cc028e4a 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.

Dan Gohman 22e9707480 Replace a few uses of SelectionDAG::getTargetNode with
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.

Owen Anderson 8c10c2482a TwoAddressInstructionPass doesn't really require LiveVariables, it just needs to update it if it's already around.

Chuck Rose III 6d161f1fd3 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 Looks like the x64 projects got out of date and this brings them up to code.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.

Owen Anderson abfd3a8162 Use ADCE instead of just DCE. ADCE will better clean up after jump threading,
for instance.

Owen Anderson 488b89f608 Use df_ext_iterator to capture the reachable set without allocating an extra set.
Also, move large sets and vectors out of instance variables and onto the stack,
and give them more reasonable sizes.

Duncan Sands 739a0548c4 Add a new getMergeValues method that does not need
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.

Owen Anderson 9edcf24da9 Use DenseSet rather than SmallPtrSet for the alive set. Using SmallPtrSet
with a huge "size" parameter is actually quite inefficient.

Chris Lattner 6b2c4f6143 instead of aborting on shifts of i1, just implicitly fold them.
The dag combiner can produce a shift of i1 when folding icmp i1's.
