21ea6085dc [SimplifyCFG] Merge conditional stores
We can often end up with conditional stores that cannot be speculated. They can come from fairly simple, idiomatic code:

  if (c & flag1)
    *a = x;
  if (c & flag2)
    *a = y;
  ...

There is no dominating or post-dominating store to a, so it is not legal to move the store unconditionally to the end of the sequence and cache the intermediate result in a register, as we would like to.

It is, however, legal to merge the stores together and do the store once:

  tmp = undef;
  if (c & flag1)
    tmp = x;
  if (c & flag2)
    tmp = y;
  if (c & flag1 || c & flag2)
    *a = tmp;

The real power in this optimization is that it allows arbitrary length ladders such as these to be completely and trivially if-converted. The typical code I'd expect this to trigger on often uses binary-AND with constants as the condition (as in the above example), which means the ending condition can simply be truncated into a single binary-AND too: 'if (c & (flag1|flag2))'. As in the general case there are bitwise operators here, the ladder can often be optimized further too.

This optimization involves potentially increasing register pressure. Even in the simplest case, the lifetime of the first predicate is extended. This can be elided in some cases such as using binary-AND on constants, but not in the general case. Threading 'tmp' through all branches can also increase register pressure.

The optimization as in this patch is enabled by default but kept in a very conservative mode. It will only optimize if it thinks the resultant code should be if-convertable, and additionally if it can thread 'tmp' through at least one existing PHI, so it will only ever in the worst case create one more PHI and extend the lifetime of a predicate.

This doesn't trigger much in LNT, unfortunately, but it does trigger in a big way in a third party test suite.

e93434193f [CVP] Fold return values if possible
In my previous change to CVP (251606), I made CVP much more aggressive about trying to constant fold comparisons. This patch is a reversal in direction. Rather than being agressive about every compare, we restore the non-block local restriction for most, and then try hard for compares feeding returns.

The motivation for this is two fold:
 * The more I thought about it, the less comfortable I got with the possible compile time impact of the other approach. There have been no reported issues, but after talking to a couple of folks, I've come to the conclusion the time probably isn't justified.
 * It turns out we need to know the context to leverage the full power of LVI. In particular, asking about something at the end of it's block (the use of a compare in a return) will frequently get more precise results than something in the middle of a block. This is an implementation detail, but it's also hard to get around since mid-block queries have to reason about possible throwing instructions and don't get to use most of LVI's block focused infrastructure. This will become particular important when combined with http://reviews.llvm.org/D14263.

7e6636cb71 [StatepointLowering] Remove distinction between call and invoke safepoints
There is no point in having invoke safepoints handled differently than the
call safepoints. All relevant decisions could be made by looking at whether
or not gc.result and gc.relocate lay in a same basic block. This change will
 allow to lower call safepoints with relocates and results in a different 
basic blocks. See test case for example.

bd67564ff2 LLE 6/6: Add LoopLoadElimination pass
Summary:
The goal of this pass is to perform store-to-load forwarding across the
backedge of a loop.  E.g.:

  for (i)
     A[i + 1] = A[i] + B[i]

  =>

  T = A[0]
  for (i)
     T = T + B[i]
     A[i + 1] = T

The pass relies on loop dependence analysis via LoopAccessAnalisys to
find opportunities of loop-carried dependences with a distance of one
between a store and a load.  Since it's using LoopAccessAnalysis, it was
easy to also add support for versioning away may-aliasing intervening
stores that would otherwise prevent this transformation.

This optimization is also performed by Load-PRE in GVN without the
option of multi-versioning.  As was discussed with Daniel Berlin in
http://reviews.llvm.org/D9548, this is inferior to a more loop-aware
solution applied here.  Hopefully, we will be able to remove some
complexity from GVN/MemorySSA as a consequence.

In the long run, we may want to extend this pass (or create a new one if
there is little overlap) to also eliminate loop-indepedent redundant
loads and store that *require* versioning due to may-aliasing
intervening stores/loads.  I have some motivating cases for store
elimination. My plan right now is to wait for MemorySSA to come online
first rather than using memdep for this.

The main motiviation for this pass is the 456.hmmer loop in SPECint2006
where after distributing the original loop and vectorizing the top part,
we are left with the critical path exposed in the bottom loop.  Being
able to promote the memory dependence into a register depedence (even
though the HW does perform store-to-load fowarding as well) results in a
major gain (~20%).  This gain also transfers over to x86: it's
around 8-10%.

Right now the pass is off by default and can be enabled
with -enable-loop-load-elim.  On the LNT testsuite, there are two
performance changes (negative number -> improvement):

  1. -28% in Polybench/linear-algebra/solvers/dynprog: the length of the
     critical paths is reduced
  2. +2% in Polybench/stencils/adi: Unfortunately, I couldn't reproduce this
     outside of LNT

The pass is scheduled after the loop vectorizer (which is after loop
distribution).  The rational is to try to reuse LAA state, rather than
recomputing it.  The order between LV and LLE is not critical because
normally LV does not touch scalar st->ld forwarding cases where
vectorizing would inhibit the CPU's st->ld forwarding to kick in.

LoopLoadElimination requires LAA to provide the full set of dependences
(including forward dependences).  LAA is known to omit loop-independent
dependences in certain situations.  The big comment before
removeDependencesFromMultipleStores explains why this should not occur
for the cases that we're interested in.

05f66f37e6 CodeGen, Target: Move Mach-O-specific symbol name logic to Mach-O lowering.
A profile of an LTO link of Chrome revealed that we were spending some
~30-50% of execution time in the function Constant::getRelocationInfo(),
which is called from TargetLoweringObjectFile::getKindForGlobal() and in turn
from TargetMachine::getNameWithPrefix().

It turns out that we only need the result of getKindForGlobal() when
targeting Mach-O, so this change moves the relevant part of the logic to
TargetLoweringObjectFileMachO.

91c642526e [X86][XOP] Add support for the matching of the VPCMOV bit select instruction
XOP has the VPCMOV instruction that performs the common vector bit select operation OR( AND( SRC1, SRC3 ), AND( SRC2, ~SRC3 ) )

This patch adds tablegen pattern matching for this instruction.

07bcdf3c68 [LAA] LLE 2/6: Fix a NoDep case that should be a Forward dependence
Summary:
When the dependence distance in zero then we have a loop-independent
dependence from the earlier to the later access.

No current client of LAA uses forward dependences so other than
potentially hitting the MaxDependences threshold earlier, this change
shouldn't affect anything right now.

This and the previous patch were tested together for compile-time
regression.  None found in LNT/SPEC.

26abcb3277 [LAA] LLE 1/6: Expose Forward dependences
Summary:
Before this change, we didn't use to collect forward dependences since
none of the current clients (LV, LDist) required them.

The motivation to also collect forward dependences is a new pass
LoopLoadElimination (LLE) which discovers store-to-load forwarding
opportunities across the loop's backedge.  The pass uses both lexically
forward or backward loop-carried dependences to detect these
opportunities.

The new pass also analyzes loop-independent (forward) dependences since
they can conflict with the loop-carried dependences in terms of how the
data flows through memory.

The newly added test only covers loop-carried forward dependences
because loop-independent ones are currently categorized as NoDep.  The
next patch will fix this.

The two patches were tested together for compile-time regression.  None
found in LNT/SPEC.

Note that with this change LAA provides all dependences rather than just
"interesting" ones.  A subsequent NFC patch will remove the now trivial
isInterestingDependence and rename the APIs.

We are long past the time when this much bug for bug compatibility was
useful.

5030f311e8 Revert "Move metadata linking after lazy global materialization/linking."
This reverts commit r251926. I believe this is causing an LTO
bootstrapping bot failure
(http://lab.llvm.org:8080/green/job/llvm-stage2-cmake-RgLTO_build/3669/).

Haven't been able to repro it yet, but after looking at the metadata I
am pretty sure I know what is going on.
