jsm explained to me that the F?CE and P?TLBE instructions should
only be used "for flushing the entire data or combined cache".
The operands of F?CE/P?TLBE are "an implementation-dependent function
of the effective address", essentially an opaque data type that
varies per processor.  The operand of F?C/P?TLB is a virtual address,
so is the right thing to use for flushing a range of addresses.
