New VS 2015 package with two hot fixes

This new VS 2015 package contains updated c2.dll, link.exe, and cl.exe
binaries (four variations of each) to fix two bugs. One is a silent
bad code-gen bug:

https://connect.microsoft.com/VisualStudio/feedback/details/2291638

The other is a bug that causes randomly corrupt object files in
debug builds:
https://connect.microsoft.com/VisualStudio/feedback/details/1853228

The modification to cl.exe is purely a change to the link timestamp so
that goma will detect that this is a new toolchain.

Local testing and testing with crrev.com/1680133003 indicate that this
is working correctly. The crrev.com/1680133003 compiles failed until
goma was updated (good) and all of the tests passed. Committing this
change will cause the VS 2015 fyi builders to start using this compiler
which will let us gather data on whether the corrupt object file bug is
fixed.

This is another new toolchain that now works correctly with goma. This commit is
initially about getting coverage from the FYI bots with these toolchain fixes.
We can decide whether we're comfortable landing VS 2015 with hot fixes later.

PTAL.
