Summary:
This patch adds Windows support for a few of the llvm-config commands,
including cflags, ldflags, libs, and system-libs.
Currently llvm-config is untested, so this patch adds tests for the
commands that it fixes as well.

Summary:
This makes it possible to specify some operands as optional to the AsmMatcher.
Setting this field to true will prevent the AsmMatcher from emitting
'too few operands' errors when there are missing optional operands.

Fix the lit bug that enabled this "feature" (empty triple is substring
of all possible target triples) and change the two outliers to use the
documented * syntax.

Summary:
This patch adds a reserve call to an expensive function
(`llvm::LoadIntrinsics`), and may fix a few other low hanging
performance fruit (I've put them in comments for now, so we can
discuss).
**Motivation:**
As I'm sure other developers do, when I build LLVM, I build the entire
project with the same config (`Debug`, `MinSizeRel`, `Release`, or
`RelWithDebInfo`). However, the `Debug` config also builds llvm-tblgen
in `Debug` mode. Later build steps that run llvm-tblgen then can
actually be the slowest steps in the entire build. Nobody likes slow
builds.

Summary:
This adds a new attribute which targets can set in TableGen which causes a function to be generated which matches register alternative names. This is very similar to `ShouldEmitMatchRegisterName`, except it works on alt names.
This patch is currently used by the out of tree part of the AVR backend. It reduces code duplication greatly, and has the effect that you do not need to hardcode altname to register mappings in C++.
It will not work on targets which have registers which share the same aliases.

Summary:
r257791 disabled the test-suite export since the addition of CMakeLists.txt was
causing build failures. This patch exports the test-suite again but does so
outside the source tree so that it isn't included in the Phase[123] builds.

If a lit test has a RUN line that includes a redirection to "/dev/tty", the
redirection goes to the special device file corresponding to the console. It
is /dev/tty on UNIX-like systems and "CON" on Windows.
This patch is needed to implement a test like PR25717 (caused by the size limit
of the Windows system call WriteConsole() prior to Windows 8) where the test
only breaks when outputing to the console and won't fail if using a pipe.

This brings the compile time of Function.cpp from ~40s down to ~4s for
me locally. It also shaves off about 400KB of object file size in a
release+asserts build.
I also realized that the AMDGPU backend does not have any GCC builtin
names to match, so the extra lookup was a no-op. I removed it to silence
a zero-length string table array warning. There should be no functional
change here.
This change really ends the story of PR11951.

Here, sed is used to prepare object files for comparison via cmp. On my Darwin
15.4.0 machine, LC_CTYPE is set to UTF-8 (by default, I believe). Under these
circumstances, anything sed is made to read will be treated as UTF-8, prompting
it to signal an error if it is not, like so:
% sed s/a/b/ <(head -n1 /dev/random) >/dev/null; echo $?
sed: RE error: illegal byte sequence
1
%
To make sed work as expected, I need to set LC_CTYPE to C:
% env LC_CTYPE=C sed s/a/b/ <(head -n1 /dev/random) >/dev/null; echo $?
0
%
Without this change, sed will exit with an error for every single file that it
compares between phase 2 and phase 3, thereby making it look as if the
differences were far larger than they are.

Step one towards using a simple binary search to lookup intrinsic IDs
instead of our crazy table generated switch+memcmp+startswith code that
makes Function.cpp take about a minute to compile. See PR24785 and
PR11951 for why we should do this.
The X86 backend contains tables that need to be sorted on intrinsic ID,
so reorder those.

This is a fix for https://llvm.org/bugs/show_bug.cgi?id=22796.
The previous implementation of ClassInfo::operator< allowed cycles of classes
such that x < y < z < x, meaning that a list of them cannot be correctly
sorted, and the sort order could differ with different standard libraries.
The original implementation sorted classes by ValueName if they were otherwise
equal. This isn't strictly necessary, but some backends seem to accidentally
rely on it. If I reverse this comparison I get 8 test failures spread across
the AArch64, Mips and X86 backends, so I have left it in until those backends
can be fixed.
There was one case in the X86 backend where the observable behaviour of the
assembler is changed by this patch. This was because some of the memory asm
operands were not marked as children of X86MemAsmOperand.

instead of using symlinks
Summary:
In the past I have run into several problems with the way
`test-release.sh` creates all the subproject directories as siblings,
and then uses symlinks to stitch them all together. In some scenarios
this leads to clang not being able to find header files, etc.
This patch changes the script so it directly exports into the correct
target locations for each subproject.

r100895 landed an llvm-only change to add minix support to googletest.

Older versions of psutil (e.g. ``1.2.1`` which is the version shipped with
Ubuntu 14.04) use a different API for retrieving the child processes.
To handle this try the new API first and if that fails try the old API.
