add 32-bit Windows SkJumper backend
The most interesting part of this is getting the call to start_pipeline
to work. From there it should be just like the other x86 backend.
The 32-bit calling conventions are the same across Linux/Mac and
Windows, so that's nice. The tricky bit is that Linux and Mac
align the stack to 16 bytes, while Windows only to 4. I think
this force_align_arg_pointer attribute on start_pipeline does the trick.
This needs a guard for layout tests.
