Merge branch 'const_posix_invlists' into blead
What characters certain POSIX classes match, like [[:xdigit:]] are
compiled into a C header file, thus avoiding the necessity of reading
them in from disk at run-time. This merge makes those fully const, so
that they can get loaded as part of a read-only text segment. The sv's
that contain these are set so that SvLEN is 0; this means (from my
looking at the code without any experience in this area) that copies are
not made when they are dup'd, such as when threads are created.
A new svtype is created for inversion lists, using the single
available slot, renumbering them.
The first few commits instead use an existing svtype, repurposing
some of its fields for use by inversion lists. This was done so that
this could be done in a maintenance release, if necessary. (Their not
being fully const can interfere with -DPERL_GLOBAL_STRUCT_PRIVATE.)
And also, should it become necessary to create an svtype for some other
purpose, we can revert to that point in the branch.

To invert an inversion list, one simply unshifts a 0 to the front of it
if one is not there, and shifts off the 0 if it does have one.
The current data structure reserves an element at the beginning of each
inversion list that is either 0 or 1. If 0, it means the inversion list
begins there; if 1, it means the inversion list starts at the next
element. Inverting involves flipping this bit.
This commit changes the structure so that there is an additional element
just after the element that flips. This new element is always 0, and
the flipping element now says whether the inversion list begins at the
constant 0 element, or the one after that.
Doing this allows the flipping element to be separated in later commits
from the body of the inversion list, which will always begin with the
constant 0 element. That means that the body of the inversion list can

Also add Encode's sub-modules to known_extensions when building statically.
There is code in Configure to treat Encode specially when it is specified as

objects for each of its subdirectories. This works well with DynaLoader,
and the top level perl Makefile doesn't even notice this, because it doesn't
have to list these libraries as things it links with at compile time.
For a static link, Encode builds a separate *.a file for each of its
subdirectories. The top level Makefile *does* need to know about these, as
a static link requires them all to be listed. Hence the work-around is to
treat Encode as a set of nested modules if linked statically.
We can't do this in Makefile.SH because the various Encode submodules are
installed as separate *.a files in the tree, and so need to continue to be
treated as distinct modules in case ExtUtils::MakeMaker is asked to (re)link
a static perl with an additional extension.

Avoid needless refcount and mortialization on pp_anonhash
pp_anonhash can be used to construct both bare hashes and hashrefs. In
the hashref case, it used to create an HV and mortalize it. Then it went
through the parameters on the stack and copied them into the hashref.
This can throw exceptions which would make the HV leak if it hadn't been
mortalized.
After potentially copying the arguments, pp_anonhash would then in the
hashREF case increment the refcount on the HV *again*, create an RV for
the HV, and mortalize that RV before pushing it on the stack.
Instead, we can get away with constructing the HV and only mortalizing
it if there's no mortalizable ref to clean up if there's an exception.

Fix regex seqfault 5.18 regression
This segfault is a result of an optimization that can leave the
compilation in an inconsistent state.
/f{0}/
doesn't match anything, and hence should be removable from the regex for
all f. However,
qr{(?&foo){0}(?<foo>)}
caused a segfault. What was happening prior to this commit is that
(?&foo) refers to a named capture group further along in the regex.
The "{0}" caused the "(?&foo)" to be discarded prior to setting up the
pointers between the two related subexpressions; a segfault follows.
This commit removes the optimization, and should be suitable for a
maintenance release.
One might think that no one would be writing code like this, but this
example was distilled from machine-generated code in Regexp::Grammars.
Perhaps this optimization can be done, but the location I chose for
checking it was during parsing, which turns out to be premature. It
would be better to do it in the optimization phase of regex compilation.
Another option would be to retain it where it was, but for it to operate
only on a limited set of nodes, such as EXACTish, which would have no
unintended consequences. But that is for looking at in the future; the

Reinstate UTF8f
This format string allows char*s to be interpolated with the
utf8ness and length specified as well, avoiding the need to create
extra SVs:
Perl_croak(aTHX_ "Couldn't twiggle the twoggle in \"%"UTF8f"\"",
UTF8fARG(is_utf8, len, s));
This is the second attempt.
I screwed up in commits
1c8b67b38f0a5 and
b3e714770ee1 because
I didn’t really understand how varargs functions receive their
arguments.
They are like structs, in that different members can be different
sizes. So therefore both ends--the caller and the called--*must* get
the casts right, or the data will be corrupted.
The main mistake I made was to use %u in the format for the first
argument and then retrieve it as UV (a simple typo, I meant unsigned
int or U32--I don’t remember).
To be on the safe side, I added a UTF8fARG macro (after SVfARG), which
(unlike SVfARG) takes three arguments and casts them explicitly, mak-
ing it much harder to get this wrong at call sites.

[perl #117535, #76910] Fix bogus ambiguity warnings
‘Ambiguous use of * resolved as operator *’: This message can occur in
cases where there is no multiplication operator, so what it is saying
is completely wrong.
When the lexer parses a bareword, it looks at the previous character
and warns if it happens to match /[*%&]/, so foo**bar and foo&&bar
result in this warning, as does print $%foo.
The purpose of the code is to catch *bar *bar or &black &sheep.
To avoid false positives, when emitting one of the three operators
* % & the lexer can record that fact, so when it sees a bareword pre-
ceded by one of those three characters, instead of guessing that the
infix operator was used, it will *know*.
The test cases added also trigger ‘Bareword found where operator
expected’. I don’t know whether that should change, but at least the
current behaviour is tested, so we will know when it does change.
