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.

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.

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.

This patch changes the generation of CGFunctionInfo to contain
the FunctionProtoType if it is available. This enables the code
generation for call instructions to look into this type for
exception information and therefore generate better quality
IR - it will not create invoke instructions for functions that
are know not to throw.

Right now clang_Cursor_getMangling will attempt to mangle any
declaration, even if the declaration isn't mangled (extern C). This
results in a partially mangled name which isn't useful for much. This

declaration isn't mangled.

hard coding /usr makes little sense for mingw-w64.
If we have portable toolchains having /usr breaks that.
If the clang we use is in /usr/bin or /usr/sbin etc this will
still detect as though it was hard coded to /usr
This makes the most sense going forward for mingw-w64 toolchains

The pointer returned by __RTDynamicCast must be bitcasted. However, it
was not expected that __RTDynamicCast would be invoked, resulting in the

value was from.
