68e044e81a Add a form of addPreserved which takes a string argument, to allow passes 
to declare that they preserve other passes without needing to pull in
additional header file or library dependencies. Convert MachineFunctionPass
and CodeGenLICM to make use of this.

"LoopVR's logic was copied into ScalarEvolution::getUnsignedRange and 
::getSignedRange. Please delete LoopVR."

a8e8c8a28f bugfix. The target may use virtual registers that aren't tracked for re-use but are allocated by the scavenger. The re-use algorithm needs to watch for that.

e36facef86 In instcombine's debug output, avoid printing ADD for instructions that are 
already on the worklist, and print Visited when an instruction is about to be
visited.  Net, on one input, this reduced the output size by at least 9x.

132727997c Remove LazyLiveness from the tree. It doesn't work right now, and I'm not going to have the time 
to finish it any time soon.  If someone's interested it, they can resurrect it from SVN history.

c0d0a1ec58 Add another bit of the ARM target assembler to llvm-mc to parse registers 
with writeback, things like "sp!", etc.  Also added some more stuff to the
temporarily hacked methods ARMAsmParser::MatchRegisterName and
ARMAsmParser::MatchInstruction to allow more parser testing.

b95136e649 Replace TargetInstrInfo::isInvariantLoad and its target-specific 
implementations with a new MachineInstr::isInvariantLoad, which uses
MachineMemOperands and is target-independent. This brings MachineLICM
and other functionality to targets which previously lacked an
isInvariantLoad implementation.
