Enable layering check in unavailable modules.
If a header file belonging to a certain module is not found on the
filesystem, that header gets marked as unavailable. Now, the layering
warning (-fmodules-decluse) should still warn about headers of this
module being wrongfully included. Currently, headers belonging to those
modules are just treated as not belonging to modules at all which means
they can be included freely from everywhere.
To implement this (somewhat) cleanly, I have moved most of the layering
checks into the ModuleMap. This will also help with showing FixIts
later.

We used to check only the buffer size, so if the new remapped buffer has the

and we did not rebuild the preambule, which sometimes caused us to crash.

clang-format: Increase penalty for breaking comments.
Unexpectedly, it seems that people commonly know what they were doing
when writing a comment.
Also, being more conservative about comment breaking has the advantage
of giving more flexibility. If a linebreak within the comment can
improve formatting, the author can add it (after which clang-format
won't undo it). There is no way to override clang-format's behavior if
it breaks a comment.

[CMake][Standalone] Rewrite standalone build based on llvm-config. CLANG_PATH_TO_LLVM_*(s) are deprecated.
Checked on VS10(multiconfig) and some singleconfig builders.
* Assumptions
- You should specify llvm-config as LLVM_CONFIG.
CMake could find one in $PATH by default.
- ENABLE_ASSERTIONS obeys LLVM's.
* Use cases
a) With LLVM build tree
Assume llvm-config is in your build tree.
Everything should work as ever.
b) With *installed* LLVM
Assume distributions. The source tree can be optional.
b1) The source tree is provided on the location `llvm-config --src-root`
- Test utils, FileCheck &c., are imported and built in the new tree.
- Gtest is built in the tree if gtest library is not found.
- Lit is used in $(SRCROOT)/utils/lit/lit.py.
b2) The source tree is not provided
- clang and utilities can be built.
- All tests, unittests and check-clang are invalidated and not built.

Refactor the Microsoft inheritance attribute handling so that it no longer has special treatment. Also fixes a minor bug where the attributes were being parsed as though they were GNU-style attributes when they were in fact keyword attributes.
This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings. By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent. It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.
This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated". It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
(e.g., "function" instead of "destructor"). By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away. This diagnostic can likely be further wordsmithed
to be shorter.

Require the type of a by-copy capture to be complete before creating its field.
The problem here is more serious than the fix implies. Adding a field
to a class updates the triviality bits for the class (among other
things). Failing to require a complete type before adding the field
meant that these updates don't happen in the well-formed case where
the capture is an uninstantiated class template specialization,
leading the lambda itself to be treated as having a trivial copy
constructor when it shouldn't. Fixes <rdar://problem/15560464>.

This commit kills off custom type specifier and keyword handling of OpenCL C
data types.
Although the OpenCL spec describes them as keywords, we can handle them more
elegantly as predefined types. This should provide better error correction and
code completion as well as simplifying the implementation.
The primary intention is however to simplify the C/C++ parser and save some
packed bits on AST structures that had been extended in r170432 just for

First we would check on ~S() and error about the ambigous delete functions,
and then we would error about using the deleted destructor.
If the destructor is deleted, there's no need to check it.
Also, move the check from Sema::ActOnFields to CheckCompleteCXXClass. These
are run at almost the same time, called from ActOnFinishCXXMemberSpecification.
However, CHeckCompleteCXXClass may mark a defaulted destructor as deleted, and
if that's the case we don't want to check it.
