toke.c: Potentially avoid work when converting to UTF-8
Some code points < 256 are the same whether represented in UTF-8, or
not. Others change to require 2 bytes to represent in UTF-8. When
parsing a string, using UTF-8 is avoided unless necessary, because of
the extra overhead required for processing UTF-8. This means that when,
during the parse, we discover we need to convert to UTF-8, we have to,
in effect, reparse whatever we have so far to make sure those code
points that differ under UTF-8 get their proper representation. This
reparsing would not be necessary if we know that the string doesn't have
such code points.
It turns out that keeping track of having seen UTF-8 variant code points
is cheap, requiring no extra branch instructions. And the payoff is
potentially large, avoiding having to reparse the string. This commit
changes to keep track.

toke.c: Reorder if/else branches
It is easier to read code if the trivial branch is follows immediately
after the 'if'.
