Primary reason to do this is to make codegen using the swizzle names in
bifrost/ISA.xml simpler. A secondary benefit is that dependent code can
now use the swizzle name that matches the context, making things a
little more readable.
We may want to consider giving widens separate values later, so that
va_lower_constants and bi_opt_constant_fold can fold them correctly, but
I don't know of current bugs caused by this.
