Reid Kleckner acbbf4bf78 Revert r337635 "[Driver] Sanitizer support based on runtime library presence"
This change causes issues with distributed build systems, which may only
have compiler binaries without any runtime libraries. See discussion

Mandeep Singh Grang e9ddc44a60 [OpenEmbedded] Fix lib paths for OpenEmbedded targets
Summary:
The lib paths are not correctly picked up for OpenEmbedded sysroots (like arm-oe-linux-gnueabi) for 2 reasons:

1. OpenEmbedded sysroots are of the form <sysroot>/usr/lib/<triple>/x.y.z. This form is handled in clang but only for Freescale vendor.

2. 64-bit OpenEmbedded sysroots may not have a /usr/lib dir. So they cannot find /usr/lib64 as it is referenced as /usr/lib/../lib64 in clang.

This is a follow-up to the llvm patch: D48861

George Karpenkov 8d12fc1907 [Driver] Sanitizer support based on runtime library presence
The runtime libraries of sanitizers are built in compiler-rt, and Clang
can be built without compiler-rt, or compiler-rt can be configured to
only build certain sanitizers. The driver should provide reasonable
diagnostics and not a link-time error when a runtime library is missing.

This patch changes the driver for OS X to only support sanitizers of
which we can find the runtime libraries. The discussion for this patch
explains the rationale

Petr Hosek 887f26d470 Support for multiarch runtimes layout
This change adds a support for multiarch style runtimes layout, so in
addition to the existing layout where runtimes get installed to:

lib/clang/$version/lib/$os

Clang now allows runtimes to be installed to:

lib/clang/$version/$target/lib

This also includes libc++, libc++abi and libunwind; today those are
assumed to be in Clang library directory built for host, with the
new layout it is possible to install libc++, libc++abi and libunwind
into the runtime directory built for different targets.

The use of new layout is enabled by setting the
LLVM_ENABLE_RUNTIME_TARGET_DIR CMake variable and is supported by both
projects and runtimes layouts. The runtimes CMake build has been further
modified to use the new layout when building runtimes for multiple
targets.

Peter Collingbourne 374599cf23 [CFI] Force LLVM to die if the implicit blacklist files cannot be found.
Currently LLVM CFI tries to use an implicit blacklist file, currently
in /usr/lib64/clang/<version>/share. If the file is not there, LLVM
happily continues, which causes CFI to add checks to files/functions
that are known to fail, generating binaries that fail. This CL causes
LLVM to die (I hope) if it can't find these implicit blacklist files.

If the CUDA toolkit is not installed to its default locations

This is tedious and the driver can be smarter if well-known tools
(like ptxas) can already be found in the PATH environment variable.

Add option --cuda-path-ignore-env if the user wants to ignore
set environment variables. Also use it in the tests to make sure
the driver always finds the same CUDA installation, regardless
of the user's environment.

Fedor Sergeev faa0a82416 [Solaris] gcc toolchain handling revamp
Summary:
General idea is to utilize generic (mostly Generic_GCC) code
and get rid of Solaris-specific handling as much as possible.

In particular:
- scanLibDirForGCCTripleSolaris was removed, relying on generic
  CollectLibDirsAndTriples

- findBiarchMultilibs is now properly utilized to switch between
   m32 and m64 include & lib paths on Solaris

- C system include handling copied from Linux (bar multilib hacks)

Fixes PR24606.

Serge Pavlov 208ac6547c Enable configuration files in clang
Clang is inherently a cross compiler and can generate code for any target
enabled during build. It however requires to specify many parameters in the
invocation, which could be hardcoded during configuration process in the
case of single-target compiler. The purpose of configuration files is to
make specifying clang arguments easier.

A configuration file is a collection of driver options, which are inserted
into command line before other options specified in the clang invocation.
It groups related options together and allows specifying them in simpler,
more flexible and less error prone way than just listing the options
somewhere in build scripts. Configuration file may be thought as a "macro"
that names an option set and is expanded when the driver is called.

Use of configuration files is described in `UserManual.rst`.
