Matt Arsenault fa7cd549d6 clang: Guess at some platform FTZ/DAZ default settings
This is to avoid performance regressions when the default attribute
behavior is fixed to assume ieee.

I tested the default on x86_64 ubuntu, which seems to default to
FTZ/DAZ, but am guessing for x86 and PS4.

Kristina Brooks b18cb9c471 [Gnu toolchain] Look at standard GCC paths for libstdcxx by default
Linux' current addLibCxxIncludePaths and addLibStdCxxIncludePaths
are actually almost non-Linux-specific at all, and can be reused
almost as such for all gcc toolchains. Only keep
Android/Freescale/Cray hacks in Linux's version.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Petr Hosek 8d612149db [Driver] Allow drivers to add multiple libc++ include paths
This allows toolchain drivers to add multiple libc++ include paths akin
to libstdc++. This is useful in multiarch setup when some headers might
be in target specific include directory. There should be no functional
change.

Erich Keane bb322555af For Linux/gnu compatibility, preinclude <stdc-predef.h> if the file is available
As reported in llvm bugzilla 32377.
Here’s a patch to add preinclude of stdc-predef.h.

The gcc documentation says “On GNU/Linux, <stdc-predef.h> is pre-included.” See https://gcc.gnu.org/gcc-4.8/porting_to.html;

The preinclude is inhibited with –ffreestanding.

Basically I fixed the failing test cases by adding –ffreestanding which inhibits this behavior.

I fixed all the failing tests, including some in extra/test, there's a separate patch for that which is linked here

Note: this is a recommit after a test failure took down the original (r318669)

David L. Jones f561abab56 [Driver] Consolidate tools and toolchains by target platform. (NFC)
Summary:
(This is a move-only refactoring patch. There are no functionality changes.)

This patch splits apart the Clang driver's tool and toolchain implementation
files. Each target platform toolchain is moved to its own file, along with the
closest-related tools. Each target platform toolchain has separate headers and
implementation files, so the hierarchy of classes is unchanged.

There are some remaining shared free functions, mostly from Tools.cpp. Several
of these move to their own architecture-specific files, similar to r296056. Some
of them are only used by a single target platform; since the tools and
toolchains are now together, some helpers now live in a platform-specific file.
The balance are helpers related to manipulating argument lists, so they are now
in a new file pair, CommonArgs.h and .cpp.

I've tried to cluster the code logically, which is fairly straightforward for
most of the target platforms and shared architectures. I think I've made
reasonable choices for these, as well as the various shared helpers; but of
course, I'm happy to hear feedback in the review.

There are some particular things I don't like about this patch, but haven't been
able to find a better overall solution. The first is the proliferation of files:
there are several files that are tiny because the toolchain is not very
different from its base (usually the Gnu tools/toolchain). I think this is
mostly a reflection of the true complexity, though, so it may not be "fixable"
in any reasonable sense. The second thing I don't like are the includes like
"../Something.h". I've avoided this largely by clustering into the current file
structure. However, a few of these includes remain, and in those cases it
doesn't make sense to me to sink an existing file any deeper.
