Summary:
@kcc: I know you've accepted the other revision, but since this is a
non-trivial change, I'm updating it to show why D24029 would help.
This commit sets up the infrastructure to use reified error
descriptions, and moves ReportStackOverflow to the new system.
After we convert all the errors, we'll be able to simplify ScopedInErrorReport
and remove the older debugging mechanism which had some errors partly reified
in some way. We'll be able to maintain the external API.
ScopedInErrorReport will be able to track one of the reified errors at a time.
The purpose of this is so we have its destructor actually print the error and
possibly interface with the debugger (will depend on the platform, of course).

Summary:
This is needed so we can use it for D23672 on VS2013, since this VS
version doesn't support unrestricted unions, and doesn't allow us to
uses an object without a trivial default constructor inside a union.

Summary:
We are going to use store instructions to poison some allocas.
Runtime flag will require branching in instrumented code on every lifetime
intrinsic. We'd like to avoid that.

My attempt to disable this test on i386 by adding "UNSUPPORTED: i386-apple"
in r279880 wasn't succesful, so I'm using REQUIRES instead.

atos currently doesn't work well when loaded from 32-bit binaries, which
was causing some of the bots to fail. Disable this test until we can
come up with a better fix.

This patch builds on LLVM r279776.
In this patch I've done some cleanup and abstracted three common steps runtime components have in their CMakeLists files, and added a fourth.
The three steps I abstract are:
(1) Add a top-level target (i.e asan, msan, ...)
(2) Set the target properties for sorting files in IDE generators
(3) Make the compiler-rt target depend on the top-level target
The new step is to check if a command named "runtime_register_component" is defined, and to call it with the component name.
The runtime_register_component command is defined in llvm/runtimes/CMakeLists.txt, and presently just adds the component to a list of sub-components, which later gets used to generate target mappings.
With this patch a new workflow for runtimes builds is supported. The new workflow when building runtimes from the LLVM runtimes directory is:
> cmake [...]
> ninja runtimes-configure
> ninja asan
The "runtimes-configure" target builds all the dependencies for configuring the runtimes projects, and runs CMake on the runtimes projects. Running the runtimes CMake generates a list of targets to bind into the top-level CMake so subsequent build invocations will have access to some of Compiler-RT's targets through the top-level build.
Note: This patch does exclude some top-level targets from compiler-rt libraries because they either don't install files (sanitizer_common), or don't have a cooresponding `check` target (stats).

Depends on D21612 which implements the building blocks for the compiler-rt
implementation of the XRay runtime. We use a naive in-memory log of fixed-size
entries that get written out to a log file when the buffers are full, and when
the thread exits.
This implementation lays some foundations on to allowing for more complex XRay
records to be written to the log in subsequent changes. It also defines the format
that the function call accounting tool in D21987 will start building upon.
Once D21987 lands, we should be able to start defining more tests using that tool
once the function call accounting tool becomes part of the llvm distribution.

This should un-break users that have not re-generated their CMake

This patch adds 48-bits VMA support for msan on aarch64. As current
mappings for aarch64, 48-bit VMA also supports PIE executable.
Tested on 39 and 48-bit VMA kernels on aarch64.

This patch adds 48-bits VMA support for msan on aarch64. As current
mappings for aarch64, 48-bit VMA also supports PIE executable. The
48-bits segments only cover the usual PIE/default segments plus some
more segments (262144GB total, 0.39% total VMA). Memory avaliability
can be increase by adding multiple application segments like 39 and
42 mapping (some mappings were added on this patch as well).
Tested on 39 and 48-bit VMA kernels on aarch64.

Summary:
Since we generate the compiler invocation on our own, we need to
manually add -target if CMAKE_C_COMPILER_TARGET has been specified.

and x86_64h-apple.
Mark the test as UNSUPPORTED to fix a bot that is failing.
http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_check
The bot is failing because asan_symbolize.py cannot tell whether the
reported address is from an x86_64 slice or an x86_64h slice by the
length of the address alone, so it ends up passing the wrong arch to
atos.
