Passing inconsistent munaligned-access / mno-unaligned-access
flags, intentionally resulted in a warning and the flag
no-unaligned-access being used.

Gcc does, at least in practice, use the last flag in such a
case. This patch updates clang behaviour accordingly; use the
last flag or base alignment behaviour on the target (which
llvm will do if no flag is explicitly passed)

Summary:
We would not perform substitution at an appropriate point, allowing strange
results to appear. We would accepts things that we shouldn't or mangle things incorrectly.  Note that this hasn't fixed the other cases like
template-template parameters or non-type template parameters.

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

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".
