mktables: refactor to eliminate a pass over tables
This patch is mainly for performance, but in eliminating a pass which
modified the tables, it allows for later changes to not have to rely on
things happening in a certain order.
Previously, tables that had special ranges in them, such as mappings to
multiple characters and character names that are algorithmically
derivable had a separate pass to process those ranges ahead of the main
table, as the information about these is output at the beginning of the
file.
What this patch does is to add a call-back for the processing of
the main body to call when it finds a special range that it doesn't
handle. That call-back just adds the information to various
temporaries, depending on what the range is.
After the processing of all the ranges, those temporaries hold all the
information needed to output the specials data. This is processed and
the text is unshifted to the beginning of the output.
pre_body() used to process all this. But it has been split up. The
code that does need to go at the beginning is moved to the write()
routine for the sub-class, which processes it before calling the super
class's write. The code that figured out about the special ranges is
moved to the new call-back handle_special_range(). The remaining code
remains in pre_body(), but it is now called later in the process.

has already returned TRUE, which will only be possible if PL_curpm and ST(0)
are valid.
Case 2 would be the case SAVEt_HELEM in Perl_leave_scope(). However, this
case is only reached as part of the unwinding from Case 1 above, so again
PL_curpm and ST(0) will be valid, for this dynamic scope.
This commit is the patch proposed in RT ##77610. It does not resolve all issues
in that ticket.
Currently C<local $1> is legal - it's a runtime no-op, which neither errors
*nor* resets $1 to undef. Clearly C<local $+{k}> is inconsistent with this,
(as it errors at scope exit for all cases, and additionally errors at local
time if $+{k} exists) but I consider it not worth fixing until we decide
whether C<local $1>'s current behaviour is a "bug" or a "feature".

Correct mistaken references to &PL_sv_true and &PL_sv false in perlguts
Their correct names are &PL_sv_yes and &PL_sv_no.

Allow mro_isa_changed_in to be called on nonexistent packages
This is necessary for an upcoming bug fix.
(For this bug:
@left::ISA = 'outer::inner';
@right::ISA = 'clone::inner';
*clone:: = \%outer::;
print left->isa('clone::inner'),"\n";
print right->isa('outer::inner'),"\n";

This commit actually replaces mro_isa_changed_in with
mro_isa_changed_in3. See the docs for it in the diff for mro.c.

Avoid calling Gcovert() when stringifying 0.0 and -0.0
Previously we always called Gconvert(), then tested its string output, then
fixed that up if necessary. This way has fewer tests. We can also reduce the
memory allocation for the string output for the case of zero.
