John Stiles 7b2b858bef Avoid short/ushort in MSL code generator.
The Metal code generator has historically avoided low-precision types in
the final output in order to dodge a variety of type-coercion issues.
However, the workaround was only coded for half/float. Extended the
workaround to cover int/short and uint/ushort as well.
