zink: enable loop unrolling for loops that have soft fp64

The info that a loop contains fp64 ops is lost after full
software lowering.
Therefore, specifically unroll these loops in zink instead of
in vulkan, where the blown up body is no longer unrolled.
This helps a lot in KHR-Single-GL46.arrays_of_arrays_gl.SubroutineFunctionCalls2.
