Vectorizer/PassManager:  I am working on moving the vectorizer out of the SCC passes. This patch moves the SLP-vectorizer and BB-vectorizer back into SCC passes for two reasons:
1. They are a kind of cannonicalization.
2. The performance measurements show that it is better to keep them in.

There should be no functional change if you are not enabling the LateVectorization mode.

When sysroot is not set, look for libstdc++ first on the clang install
directory. Before this change if clang was installed alongside a gcc with
the same version as the system one we would select the system libstdc++.

Unfortunately this is hard to test as only the non-sysroot case is changed.

We were creating undefined atoms for common symbols by mistake. That did not
lead to a link failure, for undefined atoms would be resolved by common symbols
in the same file, but that's a waste of resource.

Mode is now handled as a non-inheritable attribute, and CUDADevice & CUDAHost are now handled as inheritable attributes.  In all three cases, this makes the processing behavior more consistent with the declared behavior in Attr.td.

Adding VCIncludeDir and WindowsSDKDir to the msbuild configuration file.  This allows clang to find windows.h and other files in the

We scanned the symbol table twice; first to gather all regular symbols, and
second to process aux symbols. That's a bit inefficient and complicated. We
can instead cache aux symbols in the first pass, to eliminate the need of the
second pass.

[doxygen] Add a few missing variables to the doxygen.cfg.in for external search and cleaned up external_search_map.

[doxygen] Use correct variable names for external variable configuration and make EXTRA_SEARCH_MAPPINGS a "dumb" variable.

I do not think the massaging that I was doing for EXTRA_SEARCH_MAPPINGS was
truly necessary.

hasRelatedResultType() as it knows of methods which have
related result type by default. Such methods do not need
a redundant 'instancetype'.

Both functions will take a Type pointer instead of a Decl pointer. This helps
with follow-up type uniquing patches, which need the Type pointer to call
CXX mangler to generate unique identifiers.

No functionality change.

llvm-svn: 189519

Right now, the output for Itanium vs. Microsoft is the same. Once we start
calling mangler to get the unique identifier, this testing case will require
support for uuid mangling.

Apparently, gcc's -traditional-cpp behaves slightly differently in C++ mode;
specifically, it discards "//" comments.  Match gcc's behavior.

(e.g., all -init* methods), no need to suggest "instancetype" because it 
is redundant.

We translate these into #define directives; to preserve gcc-compatible
semantics (where the expanded macro includes the backslash), we add
an extra "\\\n" to the end of the synthesized "#define".

Summary:
Add support for eachOf/allOf/anyOf variadic matchers in the dynamic layer.
These function require some late binding behavior for the type conversions, thus changes in VariadicValue's MatcherList.
Second try. This time with a fix for C++11 builds.

When unrolling is disabled in the pass manager, the loop vectorizer should also
not unroll loops. This will allow the -fno-unroll-loops option in Clang to
behave as expected (even for vectorizable loops). The loop vectorizer's
-force-vector-unroll option will (continue to) override the pass-manager
setting (including -force-vector-unroll=0 to force use of the internal
auto-selection logic).

In order to test this, I added a flag to opt (-disable-loop-unrolling) to force
disable unrolling through opt (the analog of -fno-unroll-loops in Clang). Also,
this fixes a small bug in opt where the loop vectorizer was enabled only after
the pass manager populated the queue of passes (the global_alias.ll test needed
a slight update to the RUN line as a result of this fix).
