1cb1107c66 R600: Fix typo in R600Schedule.td
This should only make a difference in programs that use a lot of the
vector ALU instructions like BFI_INT and BIT_ALIGN.  There is a slight
improvement in the phatk bitcoin mining kernel with this patch on
Evergreen (vector size == 1):

1baa38147a Add an autoconf option for turning on -gsplit-dwarf by default
when building llvm. This saves quite a bit of time and space when
linking. Please report any problems via bugzilla.

Caveats:

a) This will only work on linux
b) This requires a fairly new binutils
c) This requires a fairly new gdb

8ba825e2ea Cleanup in unique_file when we only want the name.
This is really ugly, but it is no worse than what we have in clang right now and
it is better to get it working first and clean/optimize it afterwards.

Will be tested from clang in the next patch.

ea64122ec5 Remove all non-linker oriented compile options from the linker
command line. Change the darwin universal binary options to
be TargetCommonOpts so that they'll be passed to the linker since
-arch at least is still needed.

Someone on darwin with a buildit based build should probably verify
that this doesn't break anything there.

2e8bd89503 [PowerPC] Add predicted forms of branches
This adds support for the predicted forms of branches (+/-).
There are three cases to consider:
- Branches using a PPC::Predicate code
  For these, I've added new PPC::Predicate codes corresponding
  to the BO values for predicted branch forms, and updated insn
  printing to print them correctly.  I've also added new aliases
  for the asm parser matching the new forms.
- bt/bf
  I've added new aliases matching to gBC etc.
- bd(n)z variants
  I've added new instruction patterns for the predicted forms.

In all cases, the new patterns are used for the asm parser only.
(The new infrastructure ought to be sufficient to allow use by
the compiler too at some point.)

bc7c58d2b1 Reapply 184685 after the SetVector iteration order fix.
This should hopefully have fixed the stage2/stage3 miscompare on the dragonegg
testers.

"LoopVectorize: Use the dependence test utility class

We now no longer need alias analysis - the cases that alias analysis would
handle are now handled as accesses with a large dependence distance.

We can now vectorize loops with simple constant dependence distances.

  for (i = 8; i < 256; ++i) {
    a[i] = a[i+4] * a[i+8];
  }

  for (i = 8; i < 256; ++i) {
    a[i] = a[i-4] * a[i-8];
  }

We would be able to vectorize about 200 more loops (in many cases the cost model
instructs us no to) in the test suite now. Results on x86-64 are a wash.

I have seen one degradation in ammp. Interestingly, the function in which we
now vectorize a loop is never executed so we probably see some instruction
cache effects. There is a 2% improvement in h264ref. There is one or the other
TSCV loop kernel that speeds up.

9679c47a07 [PowerPC] Support absolute branches
There is currently only limited support for the "absolute" variants
of branch instructions.  This patch adds support for the absolute
variants of all branches that are currently otherwise supported.

This requires adding new fixup types so that the correct variant
of relocation type can be selected by the object writer.

While the compiler will continue to usually choose the relative
branch variants, this will allow the asm parser to fully support
the absolute branches, with either immediate (numerical) or
symbolic target addresses.

No change in code generation intended.

fb25071a18 [APFloat] Removed a assert from significandParts() which says that one can only access the significand of FiniteNonZero/NaN floats.
The method significandParts() is a helper method meant to ease access to
APFloat's significand by allowing the user to not need to be aware of whether or
not the APFloat is using memory allocated in the instance itself or in an
external array.

This assert says that one can only access the significand of FiniteNonZero/NaN
floats. This makes it cumbersome and more importantly dangerous when one wishes
to zero out the significand of a zero/infinity value since one will have to deal
with the aforementioned quandary related to how the memory in APFloat is
allocated.

6bf3a05235 Add a flag to defer vectorization into a phase after the inliner and its
CGSCC pass manager. This should insulate the inlining decisions from the
vectorization decisions, however it may have both compile time and code
size problems so it is just an experimental option right now.

Adding this based on a discussion with Arnold and it seems at least
worth having this flag for us to both run some experiments to see if
this strategy is workable. It may solve some of the regressions seen
with the loop vectorizer.
