Update isarev when clobbered class has subsubclasses
This fixes a case that mro_package_moved did not take into account:
If a class with multiple levels of subclasses was assigned over, then,
depending on the order in which the subclasses were processed in the
second loop in mro_package_moved, the subclasses might not be removed
from the isarev hashes of superclasses of the clobbered class.
This was because a call to mro_isa_changed_in on one class could call
mro_get_linear_isa on another class in the list, overwriting its
meta->isa hash, which is used to determine what to delete from
PL_isarev.
E.g., if D isa C isa B isa A, this assignment:
*B:: = *something::;
would cause B, C and D to be iterated over, but not in any particular
order. The order could be D, C, B, in which case mro_isa_changed_in(D)
would overwrite the meta->isa hash in C with one that did not list A.
So mro_isa_changed_in(C) would not see A in meta->isa and would not
delete PL_isarev->{A}{C}.
This commit stores the meta->isa hash as the value in the ‘big list’,
instead of the stash. The stash itself can be retrieved from the key,
since it is already a memory address (a pointer cast to a char array).
The recorded isa hash in inserted into each stash before the call to
mro_isa_changed_in.

Fix package assignment with nested aliased packages
This commit fixes package assignments like *foo:: = *bar:: when both

PATCH: [perl #78994]: optimizer loses folding
The optimizer works by creating an initial ANYOF node that is supposed
to match anything. When it finds the first node that it wants to allow
be a first match, it ANDs the anything node with that one, effectively
setting the first node to it. Subsequent nodes that could match in the
first position are OR'd instead, adding to the possibilities that the
first match could be.
But the optimizer was not dealing with the possibility of folding, so
the first node did not have that as a possibility and hence a match that
relied on the fold would not succeed.
Originally, the patch had an 'if (FOLD)' guarding the initialization of
the match anything node , but it turns out that FOLD is set only if
folding is on globally, and in the example program of the trouble
ticket, it isn't set at the proper time, because the regex is recompiled
when upgraded to utf8, and it doesn't get set then. So I
unconditionally set ANYOF_FOLD.

[perl #75176] Symbol::delete_package does not free certain memory associated with package::ISA
This commit makes @ISA changes and package aliasing update PL_isarev
properly, removing old, unnecessary entries in addition to adding new
entries. So now it is capable of shrinking, not just growing.
------------
Gory Details
------------
There is a chicken-and-egg problem when it comes to calling
mro_isa_changed_in on the affected classes: When an isa linearisation
is recalculated, it uses the existing linearisations of the super-
classes (if any) (or at least the DFS implementation does). Since an
assigned package (e.g., the *b:: in *a:: = *b::) can contain nested
packages that inherit from each other in any order (b::c isa b::c::d
or b::c::e isa b::c), this means that mro_isa_changed_in *must not* be
called on any stash while another stash contains stale data.
So mro_package_moved has been restructured. It is no longer recurs-
ive. The recursive code for iterating through nested stashes has been
moved into a separate, static routine: mro_gather_and_rename. Instead
of calling mro_isa_changed_in during the iteration, it adds all the
classes to ‘the big hash’, which mro_package_moved holds a pointer to.
When mro_gather_and_rename returns, mro_package_moved iterates through
the big hash twice: the first time to wipe caches; the second to call
mro_isa_changed_in on all the stashes.
This ‘big hash’ is now used in place of the seen_stashes that
mro_package_moved used before.
Both mro_package_moved and mro_isa_changed_in now use the existing
mrometa->isa hash to determine which classes used to be superclasses
of the stash in question. A separate routine, S_mro_clean_isarev,
deletes entries mention in isa, except for those that still exist in
the new isa hash.
mro_isa_changed_in now does two iterations through isarev, just like
mro_package_moved. It has to call get_linear_isa on the subclasses so
that it can see what is in the new meta->isa hash created thereby.
Consequently, it has to make sure that all the subclasses have their
caches deleted before it can update anything. It makes the same
changes to isarev for each subclass that are made further down on the
class for which mro_isa_changed_in was called. Yes, it is repetitive.
But calling mro_isa_changed_in recursively has more overhead and would
do more unnecessary work. (Maybe we could make some macros for this
repetitive code.)
The loop through the superclasses near the end of mro_isa_changed_in
no longer adds the subclasses to all the superclasses’ isarev hashes,
because that is taken care of further up.
------------
Side Effects
------------
One result of this change is that mro::is_universal no longer
returns true for classes that are no longer universal. I consider
that a bug fix.
-------------
Miscellaneous
-------------
This also removes obsolete comments in mro_isa_changed_in, concerning
fake and universal flags on stashes, that have been invalid since
dd69841bebe.

In B.xs refactor cc_opclassname() to make_op_object().
All bar one of the callers to cc_opclassname() were using it in the same way -
to pass as the second argument of newSVrv(), whose first argument was a new
mortal, and return value was used with sv_setiv() and PTR2IV(). So clearly
*that* is the common code needed.
Inline the existing code (all 1 line of it) in the other location that called
cc_opclassname(). As the typemap was using cc_opclassname(), replace the 4
implicit uses of it with explicit PPCODE sections. Curiously, removing the use
of this typemap actually reduces the line count of B.xs

regexec.c: Don't give up on fold matching early
As noted in the comments of the code, "a" =~ /[A]/i doesn't work currently
(except that regcomp.c knows about the ASCII characters and corrects for
it, but not always, for example in cases like "a" =~ /\p{Upper}/i. This
patch catches all those).
It works by computing a list of all characters that (singly) fold to
another one, and then checking each of those. The maximum length of
the list is 3 in the current Unicode standard.
I believe that a better long-term solution is to do this at compile
rather than execution time, by generating a closure of everything
matched. But this can't be done now because the data structure would
need to be extensively revamped to list all non-byte characters, and
user-defined \p{} matches are not known at compile-time.
And it doesn't handle the multi-char folds. There is a separate ticket
for those.

utf8.c: Add function to create inversion of swash

The function is not for public use, as it will likely be revised, so is
not in the public API, and it's name begins with underscore.
