Enable 64-bit tools with VS 2010 Express (#9981, #10722)

The Express Edition does not come with 64-bit tools, but one can install
the "Microsoft Windows SDK v7.1" to get them.  Detect this case and
check for the SDK.  If found, set PlatformToolset to use the SDK tools.
Otherwise, fail with a concise and informative error.
