toke.c: Keep better track for avoiding work in tr///
As explained in the comments, tr/// creates byte map tables for bytes
0-255 if everything is below 256. If something is higher than that,
special handling is required (currently a swash), and so there is no
point in creating the tables here by expanding each range. Prior to
this commit, it realized this on a per-range basis, not expanding ranges
which extend above 255. This commit changes that so if any time it
finds something above 255, it remembers that and skips the expansion of
all future ranges encountered.
This was done without adding any extra tests outside the specific tr///
code.

toke.c: Simplify expression
Unless there's a reason its needed, I prefer not to set a variable
within an 'if', as it increases the reader's cognitive load.

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'.

toke.c: Fix too-small SvGROW()
This might be a bug on EBCDIC, but not ASCII platforms. The code forgot
that SvGROW takes a total size, and not an incremental size. So, this
is most likely a no-op, but I believe there are no cases on ASCII
platforms where this actually needs to grow, and on EBCDIC, it would
only be very large, way above Unicode, code points. Grows in later
iterations of the loop would recover to grow to the correct size, unless
this EBCDIC escape sequence was the final thing there.

toke.c: Simplify a couple of expressions
By storing an intermediate result in a temporary, the final expression
is clearer.
