Bill Wendling 811c936ed5 Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almost 
certainly be made more generic. But it does allow us to parse something like:

          ldr     r3, [r2, r4]

correctly in Thumb mode.

Chris Lattner 58b779e9c2 Rewrite the main DSE loop to be written in terms of reasoning 
about pairs of AA::Location's instead of looking for MemDep's
"Def" predicate.  This is more powerful and general, handling
memset/memcpy/store all uniformly, and implementing PR8701 and
probably obsoleting parts of memcpyoptimizer.

This also fixes an obscure bug with init.trampoline and i8
stores, but I'm not surprised it hasn't been hit yet.  Enhancing
init.trampoline to carry the size that it stores would allow
DSE to be much more aggressive about optimizing them.

Nick Lewycky 2965d3e3cd Make @llvm.invariant.start not be readonly, so that it has side-effects. This 
unbreaks test/Transforms/InstCombine/invariant.ll which was broken by r120382.
This is a fix-forward to do what I think Chris intended.

Jakob Stoklund Olesen d4900a644c Stub out a new LiveDebugVariables pass. 
This analysis is going to run immediately after LiveIntervals. It will stay
alive during register allocation and keep track of user variables mentioned in
DBG_VALUE instructions.

When the register allocator is moving values between registers and the stack, it
is very hard to keep track of DBG_VALUE instructions. We usually get it wrong.
This analysis maintains a data structure that makes it easy to update DBG_VALUE
instructions.

Chris Lattner 9d179d911d clean up handling of 'free', detangling it from everything else.

Chris Lattner 9a146372b5 Teach basicaa that memset's modref set is at worst "mod" and never 
contains "ref".

Enhance DSE to use a modref query instead of a store-specific hack
to generalize the "ignore may-alias stores" optimization to handle
memset and memcpy.

Chris Lattner d4f1090948 two changes to DSE that shouldn't affect anything: 
1. Don't bother trying to optimize:

lifetime.end(ptr)
store(ptr)

as it is undefined, and therefore shouldn't exist.

2. Move the 'storing a loaded pointer' xform up, simplifying
  the may-aliased store code.

Bob Wilson 318ce7cb3f Fix the encoding of VLD4-dup alignment. 
The only reasonable way I could find to do this is to provide an alternate

Chandler Carruth abcab28f9b Add some dead stores to pacify my least favorite GCC warning: may be

happily add -Wno-uninitialized to the -Werror build mode. Maybe I can even do
it *only* when building with GCC instead of Clang.
