41c902fdbe Fix insertion point in pcmp expander. 
While I'm there, clean up too many \n even for me.

ef4a68badb 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.

cf82dc376a 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.

bb7b23f5b7 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.

0f53f592ad 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.

e89ada98a6 Add some dead stores to pacify my least favorite GCC warning: may be 
uninitialized. The warning is terrible, has incorrect source locations, and has
a huge false positive rate such as *all* of these.

If anyone has a better solution, please let me know. Alternatively, I'll
happily add -Wno-uninitialized to the -Werror build mode. Maybe I can even do
it *only* when building with GCC instead of Clang.

d8f717911d fix PR8686, accepting a 'b' suffix at the end of all the setcc 
instructions.  I choose to handle this with an asmparser hack,
though it could be handled by changing all the instruction definitions
to allow be "setneb" instead of "setne".  The asm parser hack is
better in this case, because we want the disassembler to produce
setne, not setneb.

706da9d8ca Move tree navigation to a new Path class that doesn't have to be a template. 
The path also holds a reference to the root node, and that allows important
iterator accessors like start() and stop() to have no conditional code. (When
the compiler is clever enough to remove it.)

5057f38141 Exploit distributive laws (eg: And distributes over Or, Mul over Add, etc) in a 
fairly systematic way in instcombine.  Some of these cases were already dealt
with, in which case I removed the existing code.  The case of Add has a bunch of
funky logic which covers some of this plus a few variants (considers shifts to be
a form of multiplication), which I didn't touch.  The simplification performed is:
A*B+A*C -> A*(B+C).  The improvement is to do this in cases that were not already
handled [such as A*B-A*C -> A*(B-C), which was reported on the mailing list], and
also to do it more often by not checking for "only one use" if "B+C" simplifies.

dd061b2854 Initialize MemDep's TD member so buildbots don't trip over an uninitialized pointer (TD is passed to PHITransAddr). 
I wonder why this didn't explode earlier.

e60d79faf7 Add a rather pointless InstructionSimplify transform, inspired by recent constant 
folding improvements: if P points to a type of size zero, turn "gep P, N" into "P".
More generally, if a gep index type has size zero, instcombine could replace the
index with zero, but that is not done here.

zero sized elements.  This allows us to compile:

  #include <string>

2f5f90ad3e Implement PR8644: forwarding a memcpy value to a byval, 
allowing the memcpy to be eliminated.

Unfortunately, the requirements on byval's without explicit 
alignment are really weak and impossible to predict in the 
mid-level optimizer, so this doesn't kick in much with current
frontends.  The fix is to change clang to set alignment on all
byval arguments.

59d2dad59e On X86, MEMBARRIER, MFENCE, SFENCE, LFENCE are not target memory intrinsics, 
so don't claim they are.  They are allocated using DAG.getNode, so attempts
to access MemSDNode fields results in reading off the end of the allocated
memory.  This fixes crashes with "llc -debug" due to debug code trying to
print MemSDNode fields for these barrier nodes (since the crashes are not
deterministic, use valgrind to see this).  Add some nasty checking to try
to catch this kind of thing in the future.
