Add/Subtract.
The following instructions are added to AArch32 instruction set:
- VQRDMLAH: Vector Saturating Rounding Doubling Multiply Accumulate
Returning High Half
- VQRDMLSH: Vector Saturating Rounding Doubling Multiply Subtract
Returning High Half
The following instructions are added to AArch64 instruction set:
- SQRDMLAH: Signed Saturating Rounding Doubling Multiply Accumulate
Returning High Half
- SQRDMLSH: Signed Saturating Rounding Doubling Multiply Subtract
Returning High Half
This patch adds intrinsic and ACLE macro support for these instructions,
as well as corresponding tests.

This adds new values for the -march option (armv8.2a and armv8.2-a,
which are aliases of each other), and new suffixes for the -march and
-mcpu options (+fp16 and +nofp16), to allow targeting the ARMv8.2-A
architecture and it's optional half-precision floating-point extension.

I spotted this by inspection in the for loop that wasn't using its iterator and was just acting on the current state repeatedly.
This appears to have been introduced as a copy and paste bug in r140763 over 4 years ago.
I have no idea how to test this. I just went back to the original commit and tried to use the variables it was using before that.

Add tests demonstrating that the analyzer supports generalized lambda capture. This
support falls out naturally from the work Gábor Horváth did adding C++11 lambdas to
the analyzer.

This prevents spurious dead store warnings when a C++ lambda is casted to a block.
I've also added several tests documenting our still-incomplete support for lambda-to-block
casts.

take a queue; some supported versions of GCC believe that this substitution
failure is an error. Instead, use a partial specialization to detect the type
of a pointer to the corresponding member. This is less general, but good enough
for our uses.

MSVC supports 'property' attribute and allows to apply it to the declaration of an empty array in a class or structure definition.
For example:
```
__declspec(property(get=GetX, put=PutX)) int x[];
```
The above statement indicates that x[] can be used with one or more array indices. In this case, i=p->x[a][b] will be turned into i=p->GetX(a, b), and p->x[a][b] = i will be turned into p->PutX(a, b, i);

The nullability checker was not suppressing false positives resulting from
inlined defensive checks when null was bound to a nonnull variable because it
was passing the entire bind statement rather than the value expression to
trackNullOrUndefValue().
This commit changes that checker to synactically match on the bind statement to
extract the value expression so it can be passed to trackNullOrUndefValue().

The Driver only checked if nostdlib was set when deciding to add
reserved_lib_stdcxx, but as nostdlib is always exactly nodefaultlibs and
nostartfiles we should be checking one (clearly nodefaultlibs in the
case) as well. This appears to be the only such instance of this in the
codebase.

This flag causes all files that were read by the compilation to be embedded
into a produced module file. This is useful for distributed build systems that
use an include scanning system to determine which files are "needed" by a
compilation, and only provide those files to remote compilation workers. Since
using a module can require any file that is part of that module (or anything it
transitively includes), files that are not found by an include scanner can be
required in a regular build using explicit modules. With this flag, only files
that are actually referenced by transitively-#included files are required to be
present on the build machine.

When RAV traverses a Stmt or Expr node, if the corresponding Traverse*
functions have not been overridden, it will now use data recursion to walk
those nodes. We arrange this to be an unobservable optimization to RAV
subclasses, and to gracefully degrade as parts of the visitation are overridden
with functions that might observe the visitation.
For instance, if an RAV subclass overrides TraverseUnaryNot, we will ensure
that there are real recursive stack frames for those traversals, but we'll
use data recursion for all other traversals.
This removes the need for DataRecursiveASTVisitor, and for the
'shouldUseDataRecursionFor' extension point, both of which are removed by this
change.
