After https://codereview.chromium.org/896583002/, the isolate step on the
64-bit bot is failing with

    MappingError: Input file C:\b\build\slave\CrWinClang64_dbg_\build\src\out\Debug_x64\x64\msvcp120d.dll doesn't exist

It looks like the x64\msvcp120d.dll only exists in 32-bit builds.
While here, also add the x64 libraries for 32-bit release builds.
