This test uses enums, which have different behavior when targeting different
systems. Specifying a triple will give predictable behavior to this test.

This is a warning about using 'assign' instead of 'unsafe_unretained'
in Objective-C property declarations. It's off by default because there
isn't consensus in the Objective-C steering group that this is the right
thing to do, but we're nonetheless okay with adding it because there's a
substantial pool of Objective-C programmers who will appreciate the warning.

This fixes formatting namespaces with preceding 'inline' and 'export' (Modules TS) specifiers.
This change fixes namespaces not being identified as such with preceding 'inline' or 'export' specifiers.
Motivation: I was experimenting with the Modules TS (-fmodules-ts) and found it would be useful if clang-format would correctly format 'export namespace'. While making the changes, I noticed that similar issues still exist with 'inline namespace', and addressed them as well.

Summary:
Added support of creating a hardlink from one file to another file.
After a hardlink is added between two files, both file will have the same:
1. UniqueID (inode)
2. Size
3. Buffer
This will bring replay of compilation closer to the actual compilation. There are instances where clang checks for the UniqueID of the file/header to be loaded which leads to a different behavior during replay as all files have different UniqueIDs.

Load Hardening.
Wires up the existing pass to work with a proper IR attribute rather
than just a hidden/internal flag. The internal flag continues to work
for now, but I'll likely remove it soon.
Most of the churn here is adding the IR attribute. I talked about this
Kristof Beyls and he seemed at least initially OK with this direction.
The idea of using a full attribute here is that we *do* expect at least
some forms of this for other architectures. There isn't anything
*inherently* x86-specific about this technique, just that we only have
an implementation for x86 at the moment.
While we could potentially expose this as a Clang-level attribute as
well, that seems like a good question to defer for the moment as it
isn't 100% clear whether that or some other programmer interface (or
both?) would be best. We'll defer the programmer interface side of this
for now, but at least get to the point where the feature can be enabled
without relying on implementation details.
This also allows us to do something that was really hard before: we can
enable *just* the indirect call retpolines when using SLH. For x86, we
don't have any other way to mitigate indirect calls. Other architectures
may take a different approach of course, and none of this is surfaced to
user-level flags.

Summary:
https://reviews.llvm.org/D46776 added better support for prefixes for the
"did you mean ...?" command line option suggestions. One of the tests was
checking against the `-debug-info-macro` option, which was failing on the
PS4 build bot. Tests would succeed against the `--help` and `--version`
options.
From https://llvm.org/devmtg/2013-11/slides/Robinson-PS4Toolchain.pdf, it
looks like the PS4 SDK forces optimizations and *could be* disabling the
`-debug-info-macro` altogether.
This diff removes `-debug-info-macro` altogether.
Patch by Arnaud Coomans!
Test Plan: untested since we do not have access to a PS4 with the SDK.

Summary:
Some `Expr` classes set up default values for the `ExprBits` of `Stmt`. These
default values are then overwritten by the parser sometimes. One example is
`InitListExpr` which sets the value kind to be an rvalue in the ctor. However,
this bit may change after the `InitListExpr` is created. There may be other
expressions similar to `InitListExpr` in this sense, thus the safest solution
is to copy the expression bits.
The lack of copying `ExprBits` causes an assertion in the analyzer engine in a
specific case: Since the value kind is not imported, the analyzer engine
believes that the given InitListExpr is an rvalue, thus it creates a
nonloc::CompoundVal instead of creating memory region (as in case of an lvalue
reference).

Given the following kernel:

the presence of 'double d', but when removed, it passes.
The expectation is that extended vector types of unsupported types
will also be unsupported.

There are two types of dynamic initializer stubs. There's
`dynamic initializer for 'x''(void)
and
`dynamic initializer for `static Foo::Bar StaticDataMember''(void)
The second case is disambiguated from the first by the presence of
a ? after the operator code. So the first will appear something like
?__E<name> while the second will appear something like ?__E?<name>.
clang-cl was mangling these both the same though. This patch
