Summary:
These two flags are in the same family as -Rpass, but are used in
different situations.

-Rpass-missed is used by optimizers to inform the user when they tried
to apply an optimization but couldn't (or wouldn't).

-Rpass-analysis is used by optimizers to report analysis results back
to the user (e.g., why the transformation could not be applied).

Depends on D3682.

No longer allow the -std options to entirely override the -x language option. This allows -x cuda -std=c++11, for instance.

With -Weverything, the backend remarks are enabled. This was
causing spurious diagnostics for remarks that we don't yet
handle (cf http://reviews.llvm.org/D3683).

This will stop being a problem once http://reviews.llvm.org/D3683
is committed.

Fixing a test case which was failing the MSVC build bots. When -std isn't specified with an MSVC build, it defaults to -std=c++11, which overrides the -x cuda option. In turn, this causes all CUDA language option checks to fail.

This fix is possibly temporary while we determine whether -x cuda should be considered along with -std=c++11 when setting language options.

member functions), ensure that the redecl chain never transitions from 'inline'
to 'not inline', since that violates an AST invariant.

Before r160106 there was a way to recursively visit all descendants of a cursor
via Cursor_visit, but it was removed. Since then, every user needs to
reimplement the recursive descent into get_children.

Adding a walk_preorder() method to Cursor that conveniently implements recursive
walking in a Pythonic way. This also greatly simplifies get_cursor and
get_cursors in tests/cindex/util.py (walk_preorder is now tested through these
utility functions, since they are used in many tests).

Clang knows about the sanitizer blacklist and it makes no sense to
add global to the list of llvm.asan.dynamically_initialized_globals if it
will be blacklisted in the instrumentation pass anyway. Instead, we should
do as much blacklisting as possible (if not all) in the frontend.

Until now all CUDA-specific attributes were represented with
CXCursor_UnexposedAttr; now they are actually implemented, including the Python
bindings.

I opened a discussion on cfe-commits.  Ideally we've got a few things 
that need to happen.  CompilerRT should probably have blacklists tests.  
Asan should probably not depend on that specific field.

Since the continuation block of the if statement is emitted within the
condition scope this had the undesirable effect of creating a line table
entry at the end of the then or else statement, a line that may have never
been executed.
