Implement optimized version of the tlb flushing routines for systems
using ASIDs. These are behind the use_asid_allocator static branch to
not affect existing systems not using ASIDs.

I still think the code duplication and exposing of new code in a global
header here is a bad idea and would suggest the version I sent instead.
