We currently use a 32-bit Rust toolchain for win32 builds, but this can lead
to OOM situations. This patch makes win32 builds use a 64-bit Rust toolchain,
which requires a little bit of extra configuration because rustc needs to
be able to find a link.exe that produces 64-bit binaries for building
things like build scripts, which are host binaries.
We will now generate a batch file that sets LIB to the paths to 64-bit
libraries and invokes the x64-targeting link.exe, and add a section to the
.cargo/config file to instruct cargo to use that batch file as the linker
when producing 64-bit binaries.

The new VS package is now based on update 15.4.2, although that release didn't affect any files in our package. I'm picking up the update mostly just to make filename unique.
This patch adds a copy of vswhere.exe to build/win32, downloaded from the
current latest release (1.0.62):
https://github.com/Microsoft/vswhere/releases/download/1.0.62/vswhere.exe
It changes toolchain.configure to invoke vswhere.exe instead of reading
the registry, since that no longer works for VS2017 (but vswhere can locate
VS2015). It also removes a layer of complexity in that code by dropping
support for non-64-bit host systems, since we don't really support building
on 32-bit Windows anymore anyway.
There's a little bit of fixup in windows.configure where some LIB paths
have changed in 2017.

The `cd $PATH && pwd` pattern doesn't work when $PATH doesn't exist, so
move them in a block only executed when the directory exists.

Visual Studio 2015 Update 3 has been out for a few months. It appears
stable. So let's start using it.
As part of this, we also update the Windows SDK to the version
corresponding with the Windows 10 Anniversary Update (10.14393.0).

autospider builds set VSPATH before sourcing
build/win*/mozconfig.vs-latest, so VSWINPATH was never set. Furthermore,
the way it sets variables for the build system relies on the variable
going through and export from mk_add_options, which
mk_export_correct_style conveniently does for us.
- Update the tooltool manifests to use the new package.
- Update mozconfig paths to reflect MSVC tooltool package changes.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

Per froydnj in bug 1186064 comment #23, "it makes sense to proceed with removing
MSVC 2013 support." This commit does that.
We also go a step further and require VS2015 Update 2 instead of just
update 1. This temporarily brings us down to just 1 officially supported
Visual Studio version. However, VS2015u3 was just released and is
unofficially supported.
Since MOZ_CRT is no longer set, references to it have been removed.

This commit switches Windows builds from Visual Studio 2013
to Visual Studio 2015 Update 1.
Previously, Visual Studio was installed on the builders as part
of the base system image. Starting with this commit, we obtain
Visual Studio from a pre-generated, self-contained archive
containing the executables, Windows SDK, and other support
files. This means that new Windows toolchains can be installed
without having to modify configuration of machines in automation!
The mozconfigs for Visual Studio 2015 are a bit different from
existing mozconfigs.
Because it appears to be completely redundant and not necessary,
the LIBPATH variable has been dropped.
The order of paths in PATH, LIB, and INCLUDE has changed. The new
order more accurately reflects what would be defined by
vcvarsall.bat.
As part of switching to Visual Studio 2015, the Universal CRT is
now required. So, the 2015 mozconfigs export WIN_UCRT_REDIST_DIR
to define the location to those files.
The switch to Visual Studio 2015 also involves the switch from
the Windows 8.1 SDK to the Windows 10 SDK. However, we still
target an old version of Windows, so this hopefully shouldn't
have any significant fallout.
It's worth noting that switching to Visual Studio 2015 makes
builds - especially PGO builds - significantly faster. Our
PGO build times in automation are ~1 hour faster. Our regular
builds appear to be a few minutes faster.

Currently it will fail with errors such as:
Insufficient debug information (private symbols are needed) or code from
unknown language. The following modules didn't have full symbols:
nsBrowserApp.obj
AppData.obj (xpcomglue_staticruntime.lib)
FileUtils.obj (xpcomglue_staticruntime.lib)
nsCRTGlue.obj (xpcomglue_staticruntime.lib)
nsXPCOMGlue.obj (xpcomglue_staticruntime.lib)
We need to turn this back on when clang-cl grows more debug
info support.
