This change looks incomplete to me. @vnkozlov: Shouldn't we remove 
`AllocatePrefetchStyle == 3` completely? 
`PhaseMacroExpand::prefetch_allocation` still mentions "BIS instruction is used 
on SPARC as prefetch". Please note that PPC64 also still has an implementation 
for it (nodes with `predicate(AllocatePrefetchStyle == 3)`). I guess that we 
don't need it any more. Maybe we should check performance again.
