Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across 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.

When symbolizing large binaries, parsing every CU in a DWP file is a
significant performance penalty. Instead, use the index to only load the
CUs that are needed.

I was a bit lazy when I first implemented this & skipped the index
lookup - obviously for large files this becomes pretty crucial, so here
we go, do the index lookup. Speeds up large DWP symbolizing by... lots.
(20m -> 20s, actually, maybe more in a release build (that was a release
build without index lookup, compared to a debug/non-release build with
the index usage))

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

This is very rudimentary support for debug_cu_index, but it is enough to
allow llvm-dwarfdump to find the offsets for contributions and
correctly dump debug_info.
It will need to actually find the real signature of the unit and build
the real hash table with the right number of buckets, as per the DWP
specification.
It will also need to be expanded to cover the tu_index as well.

This is a recommit of 252842 which was reverted in 252859. The issue was
using %s format specifier for a StringRef - used Format's
left_justify(StringRef, int) instead.
It'd be nice to have __attribute__((format(..))) on llvm::format, but
apparently it's only implemented for c-style variadics, not C++ variadic
templates. Perhaps we could fix that & conditionalize the attribute on
such...
