[MERGE] Even smaller toke

This continues the work merged in 5015bd0bb5ee7e0fa1ede1669bdfcd7bb5f10ebd,
factoring code out of Perl_yylex() and its callees, in the hope of making
the lexer easier to understand locally.

The work in the previous branch used unbounded tail recursion in some
places. Some compilers may have been able to compile the tail-recursive
calls as jumps under some optimisation modes, but we cannot rely on that. So
this further work replaces the unbounded recursion with gotos or other
control structures. It's a little annoying not to have been able to
eliminate those gotos, but these remaining gotos all occur within a function
that's considerably smaller and easier to understand, and they merely jump
all the way back to the top of that function.

After these changes, the largest remaining piece of Perl_yylex() is just
over 900 lines (down from originally >4100), and consists of a single switch
statement, all of whose case groups are independent.

This branch also contains a note in perldelta that this major refactoring
has taken place.

toke.c: replace recursive calls to yyl_try() with goto

The downside of writing these calls recursively is that not all compilers
will compile the tail-position calls as jumps; that's especially true in
earlier versions of this refactoring process (where yyl_try() took a large
number of arguments), but it's not in general something we can expect to
happen — especially in the presence of `-O0` or similar compiler options.
This can lead to call-stack overflow in some circumstances.

Most recursive calls to yyl_try() occur within yyl_try() itself, so we can
easily replace them with an explicit `goto` (which is what most compilers
would use for the recursive calls anyway, now that yyl_try() takes ≤3

There are only two other recursive-call cases. One is yyl_fake_eof(), which
as far as I can tell is never called repeatedly within a single file; this
seems safe.

The other is yyl_eol(). It has exactly two distinct return paths, so this
commit moves the retry logic into its yyl_try() caller.

With this change, we no longer seem to trigger call-stack overflow.

toke.c: Fix bug tr/// upgrading to UTF-8 in middle

Consider tr/\x{ff}-\x{100}/AB/.

While parsing, the code keeps an offset from the beginning of the output
to the beginning of the second number in the range.  This is purely for
speed so that it wouldn't have to re-find the beginning of that value,
when it already knew it.

But the example above shows the folly of this shortcut.  The second
number in the range causes the output to be upgraded to UTF-8, which
makes that offset invalid in general.  Change to re-find the beginning.

regcomp.c: Avoid reparsing a node

When it's determined that the final character of a node really should
be in the next node to avoid splitting a multi-character fold, the node
is refilled from scratch, setting an upper limit of how far to go just
before that character.

This commit changes to avoid that reparsing and refilling if just the
final character has to be omitted.  If the node has to be backed up two
or more characters, the reparsing is still done.  The technique in this
commit could be extended to avoid those, but doing it generally is
complicated, and doing it the way this commit does gets more and more
cumbersome, and the odds rapidly get smaller of needing to do more than
what I've done here.
