bug 1401647 - use a 64-bit Rust toolchain for win32 builds. r=rillian We currently use a 32-bit Rust toolchain for win32 builds, but this can lead to OOM situations. This patch makes win32 builds use a 64-bit Rust toolchain, which requires a little bit of extra configuration because rustc needs to be able to find a link.exe that produces 64-bit binaries for building things like build scripts, which are host binaries. We will now generate a batch file that sets LIB to the paths to 64-bit libraries and invokes the x64-targeting link.exe, and add a section to the .cargo/config file to instruct cargo to use that batch file as the linker when producing 64-bit binaries.
