sh: Provide a global TLB flush for U/I-TLB clear. This provides a sledgehammer approach for clearing the TLBs, only to be used in cases where we know we will never want to use the mappings again and have no interest in preserving state. This also destroys wired entries. The primary use for this is when we are either entering or exiting the kernel completely, in the latter case as a precursor for CPU reset by MMU.
