This fixes erroneously reported CUDA compilation errors
in host-side code during device-side compilation.
I've also restricted OpenMP-specific checks to trigger only
if we're compiling with OpenMP enabled.

Currently CodeGen is calling std::sort on the features vector in TargetOptions for every function, but I don't think CodeGen should be modifying TargetOptions.

These functions were defined as static members of TemplateSpecializationType.
Now they are moved to namespace level. Previously there were different
implementations for lists containing TemplateArgument and TemplateArgumentLoc,
now these implementations share the same code.
This change is a result of refactoring patch D40508. NFC.

The WebAssembly standard does not yet have threads, and while it's in the
process of being standardized, it'll take some time for it to make it
through and be available in all popular implementations. With increasing
numbers of people using the LLVM wasm backend through LLVM directly rather
than through Emscripten, it's increasingly important to have friendly
defaults.

Summary:
Switch CPU names not recognized by GNU assembler to a close CPU that it
does recognize. In this patch, kryo, falkor and saphira all get
replaced by cortex-a57 when invoking the assembler. In addition, krait
was already being replaced by cortex-a15.

We didn't support the following syntax:
(std::initializer_list<int>){12}
which suddenly produces CompoundLiteralExpr that contains
CXXStdInitializerListExpr.
Lift the assertion and instead pass the value through CompoundLiteralExpr
transparently, as it doesn't add much.

The information about access and type sizes is necessary for
producing TBAA metadata in the new size-aware format. With this
patch, D39955 and D39956 in place we should be able to change
CodeGenTBAA::createScalarTypeNode() and
CodeGenTBAA::getBaseTypeInfo() to generate metadata in the new
format under the -new-struct-path-tbaa command-line option. For
now, this new information remains unused.

Shadow stack solution introduces a new stack for return addresses only.
The stack has a Shadow Stack Pointer (SSP) that points to the last address to which we expect to return.
If we return to a different address an exception is triggered.
This patch includes shadow stack intrinsics as well as the corresponding CET header.
It includes CET clang flags for shadow stack and Indirect Branch Tracking.

fma4 instructions zero the upper bits of the xmm register. fma3 instructions leave the bits unmodified. This requires separate builtins for the different semantics.
While we're cleaning up the scalar builtins this also removes the fma3 fmsub/fnmadd/fnmsub builtins by using negates in the header file.

Summary:
clang-format does not collapse short records, interfaces, unions, etc.,
but fails to do so if the record is preceded by certain modifiers
(export, default, abstract, declare). This change skips over all
modifiers, and thus handles all record definitions uniformly.
Before:
export class Foo { bar: string; }
class Baz {
bam: string;
}
After:
export class Foo {
bar: string;
}
class Baz {
bam: string;
}

Summary:
TypeScript generic type arguments can contain object (literal) types,
which in turn can contain semicolons:
const x: Array<{a: number; b: string;} = [];
Previously, clang-format would incorrectly categorize the braced list as
a block and terminate the line at the openening `{`, and then format the
entire expression badly.
With this change, clang-format recognizes `<` preceding a `{` as
introducing a type expression. In JS, `<` comparison with an object
literal can never be true, so the chance of introducing false positives
here is very low.

Summary:
Automatic Semicolon Insertion in clang-format tries to guess if a line
wrap should insert an implicit semicolong. The previous heuristic would
not trigger ASI if a token was immediately preceded by an `@` sign:
function foo(@Bar // <-- does not trigger due to preceding @
baz) {}
However decorators can have arbitrary parameters:
function foo(@Bar(param, param, param) // <-- precending @ missed
baz) {}
While it would be possible to precisely find the matching `@`, just
conversatively disabling ASI for the entire line is simpler, while also
not regressing ASI substatially.

Two new matchers for `CXXNewExpr` are added which may be useful e.g. in

plain `new`. The other one, `hasArraySize` matches `new[]` for a given size.

This saves some cycles when compiling with "-w".
(Also fix a potential crash on invalid code for tools that tries to recover from some
errors, because analysis might compute the CFG which crashes if the code contains
invalid declaration. This does not happen normally with because we also don't perform
these analysis if there was an error.)

In the future the compiler will analyze whether the OpenMP
runtime needs to be (fully) initialized and avoid that overhead
if possible. The functions already take an argument to transfer
that information to the runtime, so pass in the default value 1.

currently being upstreamed.)
