Switch the Windows builds over to clang-cl.

This also switches them to being 64-bit, which I think is
probably acceptable in this modern age, especially for such
a non-essential piece of software. If anyone complains I can
always reinstate a parallel 32-bit build.

To support the switch to 64-bit, this commit also changes the default
install directory in the MSI to 'Program Files' rather than 'Program
Files (x86)'.
