Richard Trieu a1d7ece05c Fix macro backtrace printing.
Sometimes, a macro that expands to another macro name will not be printed in
the macro backtrace.  This patch finds the missed macro expansions and prints
them.  Fixes PR16799

Adrian Prantl 6b21ab21d1 Add a -gmodules option to the driver and a -dwarf-ext-refs to cc1
to enable the use of external type references in the debug info
(a.k.a. module debugging).

The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.

Richard Smith fb1e7f7d1a [modules] Add an experimental -cc1 feature to embed the contents of an input
file in the .pcm files. This allows a smaller set of files to be sent to a
remote build worker when building with explicit modules (for instance, module
map files need not be sent along with the corresponding precompiled modules).

This doesn't actually make the embedded files visible to header search, so
it's not useful as a packaging format for public header files.

Richard Smith 216a3bd70d [modules] Change the way we deal with .d output for explicitly-specified module
files: include the .pcm file itself in the .d output, rather than including its
own input files. Other forms of module file continue to be transparent for .d
output.

Arguably, the input files for the .pcm file are still inputs to the
compilation, but that's unnecessary for make-like build systems (where the
mtime of the .pcm file is sufficient) and harmful for smarter build systems
that know about module files and want to track only the local dependencies.

Ivan Krasin 1193f2cbc0 Add sanitizer blacklists to the rules generated with -M/-MM/-MD/-MMD.
Summary:
Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer,
Control Flow Integrity and others, use blacklists to specify which types / functions
should not be instrumented to avoid false positives or suppress known failures.

This change adds the blacklist filenames to the list of dependencies of the rules,
generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain
C/C++/ObjC files need to be recompiled (if a blacklist is updated).

Richard Trieu ecd36ee80b Stop printing macro backtraces that don't help diagnostics.
When displaying the macro backtrace, ignore some of the backtraces that do not
provide extra information to the diagnostic.  Typically, if the problem is
entirely contained within a macro argument, the macro expansion is often not
needed.  Also take into account SourceRange's attached to the diagnostic when
selecting which backtraces to ignore.  Two previous test cases have also been
updated.

Ulrich Weigand 3c5038a535 Add support for System z vector language extensions
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.

Store the locations for a macro expansion in a vector, then iterate over them
instead of using recursion.  This simplifies the logic around the backtrace

NOTE: reverts r242077 to reinstate r242058, r242065, 242067

  - Added a test for cuda pipeline creation in clang driver.

  New clang options:
  --cuda-host-only   - Do host-side compilation only.
  --cuda-device-only - Do device-side compilation only.

  --cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side
    compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more
    than once in which case one device-compilation will be done per

Pass down the -flto option to the -cc1 job, and from there into the

If we are preparing for LTO (e.g. a -flto -c compile), the new pass is not
