Change VS 2015 Update 1 package to VM version
Change VS 2015 Update 1 package to VM version

The original VS 2015 Update 1 toolchain package was created on a
development machine and was not reproducible. This package was
created on a clean VM in hopes of making it reproducible. The
steps to create it are:

Install Windows 7 Professional, 64-bit
Install VS 2015 Professional Update 1. Select custom install and these
minimum options:
- Visual C++ (which selects three sub-categories including MFC)
- Universal Windows App Development Tools
  - Tools (1.2) and Windows 10 SDK (10.0.10586)

Then download the Windows 10 SDK. The version must match the one
installed with VS 2015 Update 1 or else there will be warnings about
the need to uninstall the previous version. Select "Debugging Tools
for Windows" in addition to the defaults (Windows App Certification Kit,
Windows Software Development Kit). Note, however, that this just
downloads the installers. A message will suggest that running setup.exe
will install the requested components but actually you have to go into
the Downloads\Windows Kits\10\StandaloneSDK\Installers directory to
run the x86 and x64 debugger installers.

Then install depot_tools and run:

> python depot_tools\win_toolchain\package_from_installed.py 2015

The package is uploaded with this syntax (replace hash.zip):

> python depot_tools\third_party\gsutil\gsutil cp hash.zip
gs://chrome-wintoolchain/hash.zip

This process arguably packages up more files than are needed. The
sys32\api_ms-* files can't actually be used in this form - the Universal
Windows 10 C Runtime needs to be installed. These files are also
different on difference OSes, so packaging them doesn't really make
sense. Also the VC\lib\onecore and VC\redist\onecore files are large and
appear to be unneeded. But, removing these is not important.
