C++1y, so stop adding the 'const' there. Provide a compatibility warning for
code relying on this in C++11, with a fix-it hint. Update our lazily-written
tests to add the const, except for those ones which were testing our
implementation of this rule.

Still to do here:
  - we have a collection of syntactic accepts-invalids to diagnose
  - support non-PODs in VLAs, including dynamic initialization /
    destruction
  - runtime checks (and throw std::bad_array_length) for bad bound
  - support VLA capture by reference in lambdas
  - properly support VLAs in range-based for (don't recompute bound)

Add a CXXDefaultInitExpr, analogous to CXXDefaultArgExpr, and use it both in
CXXCtorInitializers and in InitListExprs to represent a default initializer.

There's an additional complication here: because the default initializer can
refer to the initialized object via its 'this' pointer, we need to make sure
that 'this' points to the right thing within the evaluation.

Clarifying memory allocation: approved for C++14. Move from N/A to no, since we currently relax 'operator new' calls which didn't come from new-expressions.

Implement core issue 1608: class members can be found via operator lookup in a trailing return type in that class's body.

Sourcery CodeBench and modern FSF Mips toolchains require a bit more
complicated algorithm to calculate headers, libraries and sysroot paths
than implemented by Clang driver now. The main problem is that all these
paths depend on a set of command line arguments additionally to a target
triple value. For example, let $TC is a toolchain installation directory.
If we compile big-endian 32-bit mips code, crtbegin.o is in the
$TC/lib/gcc/mips-linux-gnu/4.7.2 folder and the toolchain's linker requires
--sysroot=$TC/mips-linux-gnu/libc argument. If we compile little-endian
32-bit soft-float mips code, crtbegin.o is in the
$TC/lib/gcc/mips-linux-gnu/4.7.2/soft-float/el folder and the toolchain's
linker requires --sysroot=$TC/mips-linux-gnu/libc/soft-float/el argument.

1. Calculate MultiarchSuffix using all necessary command line options and
   use this MultiarchSuffix to detect crtbegin.o location in the
   GCCInstallationDetector::ScanLibDirForGCCTriple() routine.
2. If a user does not provide --sysroot argument to the driver explicitly,
   calculate new sysroot value based on command line options. Then use this
   calculated sysroot path:
   a. To populate a file search paths list in the Linux::Linux() constructor.
   b. To find Mips toolchain specific include headers directories
      in the Linux::AddClangSystemIncludeArgs() routine.
   c. To provide -–sysroot argument for a linker.

Note:
- The FSF's tree slightly differs (folder names) and is not supported
  yet.
- New addExternCSystemIncludeIfExits() routine is a temporary solution.
  I plan to move path existence check to the addExternCSystemInclude()
  routine by a separate commit.

Introduce a new helper function, which computes the first symbolic region in
the base region chain. The corresponding symbol has been used for assuming that
a pointer is null. Now, it will also be used for checking if it is null.

This ensures that we are tracking a null pointer correctly in the BugReporter.

- memory.MismatchedDelete, memory.MultipleDelete, and memory.DeallocateNonPtr
  are complete (unix.MismatchedDeallocator and cplusplus.NewDelete)
- Per discussion on the mailing list, different.UnaryPlusWithUnsigned has
  dubious value; remove it.
- Add potential checker ctordtor.PlacementSelfCopy per an internal bug report.
- core.AttributeNonNull is now core.NonNullParamChecker, though no one should
  be depending on this name anyway.

Microsoft's Source Annotation Language (SAL) defines a bunch of keywords
for annotating the inputs and outputs of functions.  Empty definitions
for the keywords are provided by <stdlib.h> -> <crtdefs.h> -> <sal.h>.
This makes it basically impossible to include MSVC's stdlib.h and
Clang's *mmintrin.h headers at the same time if they have variables
named __in.  As a workaround, I've renamed those variables.

This fixes the Modules/compiler_builtins.m test which was XFAILed,
presumably due to this conflict.
