308873bcb8 Add VSX Scalar loads and stores to the PPC back end
This patch corresponds to review:
http://reviews.llvm.org/D9440

It adds a new register class to the PPC back end to contain single precision
values in VSX registers. Additionally, it adds scalar loads and stores for
VSX registers.

9e31c0cf91 YAML: Enable the YAMLParser tests.
This commit enables the tests located in test/YAMLParser directory.
Those tests were never actually enabled, as llvm-lit didn't pick up the
files with the 'data' extension. The commit renames those test files to files
with the 'test' extension so that llvm-lit would find them.

This commit also modifies yaml-bench so that it returns an error status
if an error occurred during parsing. It also adds the '-use-color'
command line option to yaml-bench (to make sure that file check matches
the error messages in the output stream).

This commit modifies some of the renamed tests so that they wouldn't
fail. It gets rid of XFAILs and uses the 'not' command instead for
some of the tests that have to fail during parsing. This commit
also adds some 'FIXME' comments to a couple of tests that are
supposed to fail but currently pass because of various bugs
in the implementation of the yaml parser.

aa46024ea3 Fix information loss in branch probability computation.
Summary:
This addresses PR 22718. When branch weights are too large, they were
being clamped to the range [1, MaxWeightForBB]. But this clamping is
only applied to edges that go outside the range, so it distorts the
relative branch probabilities.

This patch changes the weight calculation to scale every branch so the
relative probabilities are preserved. The scaling is done differently
now. First, all the branch weights are added up, and if the sum exceeds
32 bits, it computes an integer scale to bring all the weights within
the range.

The patch fixes an existing test that had slightly wrong branch
probabilities due to the previous clamping. It now gets branch weights
scaled accordingly.

f575e9f902 Use intrinsic pattern to make a simpler match
This is a follow-on to r236740 where I took Andrea's advice
in D9504 to remove a redundant pattern...except that I removed
the wrong pattern!

AFAICT, there is no change in the final code produced because 
subsequent passes would clean up the extra instructions created
by the more complicated pattern.

39cf555429 [x86] eliminate unnecessary shuffling/moves with unary scalar math ops (PR21507)
Finish the job that was abandoned in D6958 following the refactoring in
http://reviews.llvm.org/rL230221:

1. Uncomment the intrinsic def for the AVX r_Int instruction.
2. Add missing r_Int entries to the load folding tables; there are already
   tests that check these in "test/Codegen/X86/fold-load-unops.ll", so I
   haven't added any more in this patch.
3. Add patterns to solve PR21507 ( https://llvm.org/bugs/show_bug.cgi?id=21507 ).

So instead of this:

  movaps	%xmm0, %xmm1
  rcpss	%xmm1, %xmm1
  movss	%xmm1, %xmm0

We should now get:

  rcpss	%xmm0, %xmm0

And instead of this:

  vsqrtss	%xmm0, %xmm0, %xmm1
  vblendps	$1, %xmm1, %xmm0, %xmm0 ## xmm0 = xmm1[0],xmm0[1,2,3]

We should now get:

  vsqrtss	%xmm0, %xmm0, %xmm0

16e7e690b7 [JumpThreading] Simplify comparisons when simplifying branches
If we have recognized that a conditional is constant at a particular location in the code (while trying to decide if we can simplify a conditional branch), we can eagerly replace that condition with a constant if it's definition is post dominated by the branch in question.

In practice, this ends up being a compile time savings at most. JumpThreading would have visited each using branch anyways. CVP would have visited the cmp itself again. Unless LVI gives up early, we shouldn't gain any addition power by doing this transformation early. What we do gain is simplicity and compile time.

9daa4b18f7 YAML: Fix crash in the skip method of KeyValueNode class.
This commit changes the 'skip' method in the 'KeyValueNode' class
to ensure that it doesn't dereference a null pointer when calling 
the 'skip' method of its value child node. It also adds a unittest
that ensures that the crash doesn't occur.

This change is motivated by a patch that implements parsing
of YAML block scalars (http://reviews.llvm.org/D9503), as one
of the unittests in that patch triggered this problem.

c58f23eeb6 Add remove method to operate on AttrBuilder instead of AttributeSet.
Prior to this change we would have to construct a temporary AttributeSet (which isn't temporary at all given that its allocated on the context), just to contain the attributes in the builder, then call remove on that.

Now we can just remove any attributes from the (lightweight and really temporary) builder itself.

Will be used in a future commit to remove some temporary attributes sets.

63134e79e6 InstrProf: Remove a function that just returns its argument (NFC)

0f04f3b213 YAML: Extract the code that skips a comment into a separate method, NFC.
This commit extracts the code that skips over a YAML comment from 
the 'scanToNextToken' method into a separate 'skipComment' method.

This refactoring is motivated by a patch that implements parsing
of YAML block scalars (http://reviews.llvm.org/D9503), as the
method that parses a block scalar reuses the 'skipComment' method.

6cc81efe93 Bitcode: Set LastDL after writing DebugLocs
Somehow I dropped this in r233585, and we haven't had `DEBUG_LOC_AGAIN`
records since.  Add it back.  Also tests that the output assembly looks
okay.

Fixes PR23436.

28b0dda32e Handle dead defs in the if converter.
We had code such as this:
  r2 = ...
  t2Bcc

label1:
  ldr ... r2

label2;
  return r2<dead, def>

The if converter was transforming this to
   r2<def> = ...
   return [pred] r2<dead,def>
   ldr <r2, kill>
   return

which fails the machine verifier because the ldr now reads from a dead def.

The fix here detects dead defs in stepForward and passes them back to the caller in the clobbers list.  The caller then clears the dead flag from the def is the value is live.
