In more recent Linux kernels with 47 bit VMAs the layout of virtual memory
for powerpc64 changed causing the address sanitizer to not work properly. This
patch adds support for 47 bit VMA kernels for powerpc64 and fixes up test
cases.

There is an associated patch for trunk.
Tested on several 4.x and 3.x kernel releases.

Previously, when linking against libcmt from the MSVC runtime,
lld-link /verbose would show "Ignoring unknown symbol record
with kind 0x1006". It turns out this was because
TypeIndexDiscovery did not handle S_REGISTER records, so these
records were not getting properly remapped.

Summary:
Make enum ModRefInfo an enum class. Changes to ModRefInfo values should
be done using inline wrappers.
This should prevent future bit-wise opearations from being added, which can be more error-prone.

It is causing sanitizer failures on llvm tests in a bootstrapped compiler. No bot link since it's currently down, but following up to get the bot up.
This reverts commit r319218.

The offset overflow check before was incorrect. It would always give the
correct result, but it was comparing the SCALED potential fixed-up offset
against an UNSCALED minimum/maximum. As a result, the outliner was missing a
bunch of frame setup/destroy instructions that ought to have been safe to
outline. This fixes that, and adds an instruction to the .mir test that
failed the old test.

This adds -std=c17, -std=gnu17, and -std=iso9899:2017 as language mode flags for C17 and updates the value of __STDC_VERSION__ to the value based on the C17 FDIS. Given that this ballot cannot succeed until 2018, it is expected that we (and GCC) will add c18 flags as aliases once the ballot passes.

This behaves similar to the __has_cpp_attribute builtin macro in that it allows users to detect whether an attribute is supported with the [[]] spelling syntax, which can be enabled in C with -fdouble-square-bracket-attributes.

This is a follow up to r319702 which records parsing invocations.
These files are not emitted by default, and the client has to specify the
invocation emission path first.

The current implementation of the nvptx runtime (to be upstreamed shortly) uses the atomicMax operation on 64-bit integers.
This is only supported in compute capabilities 3.5 and later. I've changed the clang default to sm_35.

There's no v2i1 or v4i1 kshift, and v8i1 is only supported with AVXDQ. Isel has fake patterns to extend these types to native shifts, but makes no guarantees about the value of any bits shifted in when shifting right.
This patch promotes the vector to a type that supports a native shift first and only allows inserting into the msb of a native sized shift.
I've constructed this in a way that doesn't do the promotion if we're going to fallback to using a xmm/ymm/zmm shuffle. I think I have a plan to remove the shuffle fall back entirely. In which case we this can be simplified, but I wanted to fix the correctness issue first.

Private variables are completely redefined in the outlined regions, so
we don't need to capture them. Patch adds this behavior to the
target-based regions.

This part of lldb make use of anonymous structs and unions. The usage is
idiomatic and doesn't deserve a warning. Logic in the NSDictionary and NSSet
plugins use anonymous structs in a manner consistent with the relevant Apple
frameworks.

Summary:
I also changed the message to print both the ISA and the the architecture
name for incompatible files. Previously it would be quite hard to find the
actual path of the incompatible object files in projects that have many
object files with the same name in different directories.
