Update testcases after LLVM change r243774.
Most of these had no need to check `tag:` field, but did so as a way of
getting to the `name:` field. In a few cases I've converted the `tag:`
checks to `arg:` or `CHECK-NOT: arg:`.

The new EH instructions make it possible for LLVM to generate .xdata
tables that the MSVC personality routines will be happy about. Because
this is experimental, hide it behind a -cc1 flag (-fnew-ms-eh).

Adjust to LLVM DIBuilder API changes in r243764, using
`createAutoVariable()` and `createParameterVariable()` in place of
`createLocalVariable()`. No real functionality change here.

Parsing of pragmas followed by a class member declaration is outlined into a separate function Parser::ParseCXXClassMemberDeclarationWithPragmas().

It doesn't make any sense to enable -gmlt with -gsplit-dwarf, since
-gmlt is designed for on-line symbolication (and -gsplit-dwarf normally
emits all the -gmlt data into the .o anyway - so there's nothing to
split out except redundant/duplicate info).
With this change they override each other, -gmlt -gsplit-dwarf is the
same as -gsplit-dwarf and -gsplit-dwarf -gmlt is the same as -gmlt.

Summary:
Currently, if the argument to _Pragma is not a parenthesised string
literal, the bad token will be consumed, as well as the ')', if present.
If additional bad tokens are passed to the _Pragma, this results in
extra error messages which may distract from the true problem.
The proposed patch causes all tokens to be consumed until the closing
')' or a new line, whichever is reached first.

In llvm commit r243581, a reverse range adapter was added which allows
us to change code such as
for (auto I = Fields.rbegin(), E = Fields.rend(); I != E; ++I) {
in to
for (const FieldDecl *I : llvm::reverse(Fields))
This commit changes a few of the places in clang which are eligible to use
this new adapter.

These tests were creating a modules.idx file in my clang checkout, not
the build directory or temp.
All the other tests in this directory use -fmodules-cache-path=%t so
updated these to match.

Copying the already existing code for x86 to ARM to set the correct CPU
features when using -mcpu=native. We can already detect the CPU name
but we were not setting the correct feature bits.
Moving fpu/hwdiv down to make sure they override whatever we set the
default to be.
No tests because this is native detection, and not all ARM-enabled builds
will hapen at a specific CPU, or even ARM. I have tested locally and it
works as expected.
Fixes PR12794.

The memory-sanitizer build bot reported:
==5574== WARNING: MemorySanitizer: use-of-uninitialized-value
#0 0x7f03089e15f6 in
clang::Parser::TryAltiVecTokenOutOfLine(clang::DeclSpec&,
clang::SourceLocation, char const*&, unsigned int&, bool&)
/mnt/b/sanitizer-buildbot3/sanitizer-x86_64-linux-fast/build/llvm/tools/clang/lib/Parse/ParseDecl.cpp:6290:11
This is because the "Ident_pixel" variable was uninitialized
in the getLangOpts().ZVector case, but we'd still call into
clang::Parser::TryAltiVecTokenOutOfLine, which uses the variable.
The simplest fix for this without sprinkling !getLangOpts().ZVector
checks all over the code seems to be to just initialize the variable
to nullptr; this will then do the right thing on ZVector.
Checked in to unbreak the build bots.

This patch adds support for the System Z vector built-in functions.
The API-defined header file has the name vecintrin.h.
The user-level functions are defined in the same style as the clang
version of altivec.h, making heavy use of the __overloadable__ and
__always_inline__ attributes. Where possible the functions expand to
generic operations rather than specific built-in functions, in the hope
that that form can be optimised better.
Where a built-in routine is specified to require an immediate integer
argument, the __enable_if__ attribute is used to verify the argument is
in fact constant and in the appropriate range.
Based on a patch by Richard Sandiford.

The z13 vector facility has an associated language extension,
closely modeled on AltiVec/VSX. The main differences are:
- vector long, vector float and vector pixel are not supported
- vector long long and vector double are supported (like VSX)
- comparison operators return a vector rather than a scalar integer
- shift operators behave like the OpenCL shift operators
- vector bool is only supported as argument to certain operators;
some operators allow mixing a bool with a non-bool vector
This patch adds clang support for the extension. It is closely modelled
on the AltiVec support. Similarly to the -faltivec option, there's a
new -fzvector option to enable the extensions (as well as an -mzvector
alias for compatibility with GCC). There's also a separate LangOpt.
The extension as implemented here is intended to be compatible with
the -mzvector extension recently implemented by GCC.
Based on a patch by Richard Sandiford.

OpenMP 4.1 introduces optional argument '(n)' for 'ordered' clause, where 'n' is a number of loops that immediately follow the directive.
'n' must be constant positive integer expressions and it must be less or equal than the number of the loops in the resulting loop nest.
Patch adds parsing and semantic analysis for this optional argument.

We currently don't canonicalize paths in the preprocessed files.
But we do when writing to PCH.
This causes a discrepancy on Windows with the test below.
This test fails even on unix if you change the test to use
`%S//preprocess.h`.
I am led to conclude that the invariant that this test was intending to
test has not been upheld for a while (and may never have been).
llvm-svn: 243602
Also fix completely broken and untested code which was hiding the
primary bug. The !LLVM_ON_UNIX branch of the ifdef was actually a no-op.
I ran into this in the wild. It was causing failures in our SDK build.
Ideally we'd have a perfect llvm::sys::fs::canonical, but at least this
is a step in the right direction, and fixes an obviously broken case.
In some sense the test case I've added here is an integration test. We
should have these routines thoroughly unit tested in llvm::sys::fs.

Without DR1579 implemented, the only case for -Wredundant-move is for a
parameter being returned with the same type as the function return type. Also
include a check to verify that the move constructor will be used by matching
nodes in the AST dump.

UsingShadowDecls over other declarations of the same entity in the lookup
results. This ensures that we build correct redeclaration chains for the
UsingShadowDecls (otherwise we could see assertions and other misbehavior in
modules builds, when merging combines multiple redeclaration chains for the
same entity from the same module into one chain).
llvm-svn: 243592
Dependent types can throw off the analysis for these warnings, possibly giving
conflicting warnings and fix-its. Disabling the warning in template
instantiations will prevent this problem, and will still catch the
non-dependent cases in templates.

new GV (usually NAME.1) instead of the correct NAME of the old GV. Moving comdat
