This commit adds the missing yaml-bench utility to the
makefile in utils. It was missing before and it caused
the regression tests to fail on some buildbots when llvm-lit
couldn't find yaml-bench when llvm was built without
cmake after I committed r236754.

A LambdaCapture does not have sufficient information
to correctly determine whether it is an init-capture or not.
Doing so requires knowledge held in the LambdaExpr itself.
It the case of a nested capture of an init-capture it is not
sufficient to check (as LambdaCapture::isInitCapture did)
whether the associated VarDecl was from an init-capture.
This patch moves isInitCapture to LambdaExpr and updates
Capture->isInitCapture() to Lambda->isInitCapture(Capture).

It was just detecting the existance of the value. If it gets the value correctly, we need to check that it is non-zero to see if cpu64bit_capable should be true.

Summary:
The next step is to add user-friendly control over these options
to driver via -fsanitize-coverage= option.

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.

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.

Clang regressions were caused by more stringent assertion checking
introduced by this change. Small fix needed to clang has been committed
in r236751.
llvm-svn: 236752
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.

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.

Fix two other variables that might cause the same hang fixed in r235914.
The hang is caused by constructing ManagedStatic in signalhandler. In
this case, if FileToRemove or CallBacksToRun is not contructed, it means
there is no work to do.

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

After r236617, branch probabilities are no longer guaranteed to be >= 1. This
patch makes the swich lowering code handle that correctly, without bumping the
branch weights by 1 which might cause overflow and skews the probabilities.
Covered by @zero_weight_tree in test/CodeGen/X86/switch.ll.

After recent changes, TestConcurrentEvents began timing out. This increases the timeout limit to
7m for this test, ensure the Test has enough time to complete.

Added intrinsics for the instructions. CC parameter of the intrinsics was changed from i8 to i32 according to the spec.
