If you're planning on eventually listing all of the IceTypes, you might want to
just "handle" i64 now (presumably as an error).

[Karl, 2016/01/27 23:36:42]

Because of "preprocessing" before this method is called, not all cases will be
covered. I64 for example is not. However, I will add that case in, and a TODO to
consider flattening methods into a single switch.

+    Asm->vmovrs(Dest, Src0, getPredicate());
