091cf86389 Support for function summary index bitcode sections and files. 
Summary:
The bitcode format is described in this document:
  https://drive.google.com/file/d/0B036uwnWM6RWdnBLakxmeDdOeXc/view
For more info on ThinLTO see:
  https://sites.google.com/site/llvmthinlto

The first customer is ThinLTO, however the data structures are designed
and named more generally based on prior feedback. There are a few
comments regarding how certain interfaces are used by ThinLTO, and the
options added here to gold currently have ThinLTO-specific names as the
behavior they provoke is currently ThinLTO-specific.

This patch includes support for generating per-module function indexes,
the combined index file via the gold plugin, and several tests
(more are included with the associated clang patch D11908).

633d98b8a8 [DAGCombiner] Merge SIGN_EXTEND_INREG vector constant folding methods. NCI. 
visitSIGN_EXTEND_INREG calls SelectionDAG::getNode to constant fold scalar constants but handles vector constants itself, despite getNode being capable of dealing with them.

This required a minor change to the getNode implementation to actually deal with cases where the scalars of a BUILD_VECTOR were wider integers than the vector type - which was the only extra ability of the visitSIGN_EXTEND_INREG implementation.

No codegen intended and all existing tests remain the same.

4572919871 Try to appease MSVC, NFCI. 
This time by lifting the lambda's in `createNodeFromSelectLikePHI` to
the file scope.  Looks like there are differences in capture rules
between clang and MSVC?

4487114c63 [libFuzzer] make LLVMFuzzerTestOneInput (the fuzzer target function) return int instead of void. The actual return value is not *yet* used (and expected to be 0). This change is API breaking, so the fuzzers will need to be updated.

4.9.1 -Wall.  Swallow (ASCII-)artistic integrity and use pipes instead.

79fa7ea8a7 [SCEV] Recognize simple br-phi patterns 
Summary:
Teach SCEV to match patterns like

```
  br %cond, label %left, label %right
 left:
  br label %merge
 right:
  br label %merge
 merge:
  V = phi [ %x, %left ], [ %y, %right ]
```

as "select %cond, %x, %y".  Before this SCEV would match PHI nodes
exclusively to add recurrences.

This addresses PR25005.

7db4779bd2 [CMake] We need to explicitly add llvm-config before clang so that LLVM_BUILD_EXTERNAL_COMPILER_RT can depend on llvm-config.

2354bd7d63 inariant.group handling in GVN 
The most important part required to make clang
devirtualization works ( ͡°͜ʖ ͡°).
The code is able to find non local dependencies, but unfortunatelly
because the caller can only handle local dependencies, I had to add
some restrictions to look for dependencies only in the same BB.
