Moves the build task code to a shared project that we use to build
at net45 and a portable50 CodeAnalysis MSBuild task. Also upgrades to
nuget v3.2.1-rc since this is necessary to understand the dotnet4.3 spec
used in the project.json.

This helps with build failure diagnostics. I've verified that this
added nearly-zero impact on build time.

Exit on assert failure in bootstrap build

It's always supposed to be true at this point, and only half the things
were looking at it in the first place.

...to Roslyn.VisualStudio.Setup.vsix

This changes the compilers and server to exit the process when a Debug.Assert
call fails in a bootstrap build.  The current behavior of throwing up a dialog
blocks the Jenkins build until a timeout occurs and leaves no data.  Now a full
stack trace will be printed, the process exits with a non-zero exit code and the
entire run will fail promptly.
