Now that the current toolchain is in a directory path that includes the hash of the toolchain it is much harder to run SetEnv.cmd, which is sometimes necessary to get dumpbin, or cl.exe and link.exe in the path.

We could fix this easily by having a batch file or Python script that would grab the hash from build\vs_toolchain.py and run the correct version of SetEnv.cmd. Perhaps a batch file that runs a python script that creates a batch file?
