Synopsis
Invalidates any address-translation cache entries that a subsequent
implicit memory access to guest virtual memory may use. The instruction
applies to guest virtual addresses within the range specified by xs1

identified by the ASID in xs2 otherwise. Only entries for the current
virtual machine (as identified by hgatp.VMID) are affected.
