regen/op_private: Swap two flag bit positions
This makes two flags adjacent so that the next commit can make them into
a bitfield

Log Message:
-----------
op_private: Combine two bits into a bitfield
One of these two bits is a proper subset of the other, so there is no
loss of generality in making them part of essentially an enum.
This will allow the next commit to add a third possibility without
needing an extra bit (which we don't have available).

Log Message:
-----------
Add an optimization to tr/// operating on UTF-8 strings
It is frequently the case that the operands of tr are only ASCII-range
characters, such as tr/A-Z/a-z/.
In that case, it doesn't matter if the SV they are transliterating is
encoded as UTF-8 and contains lots of non-ASCII characters. Those don't
get touched by the tr.
That means we can treat all SVs passed to this as non-UTF-8, skipping
the more expensive code that deals with UTF-8.
