regexec.c: Use compiled-in POSIX definitions
This changes the regex engine to not go out to the disk when needing to
find the definitions of POSIX classes, but to use the compiled-in ones
introduced earlier in this commit series.

lib/B/Deparse.t: Move order-dependent test
This makes TODO and moves a test to earlier in the file where it fails,
and creates a copy just after the test that causes it to succeed.

IDStart and IDCont no longer go out to disk
These are the base names for various macros used in parsing identifiers.
Prior to this patch, parsing a code point above Latin1 caused loading
disk files. This patch causes all the information to be compiled into
the Perl binary.

avoiding reading them in from disk.

Move initialization of PL_XPosix_ptrs[] to perl.c
This was performed unconditionally in regcomp.c. However, future
commits will use this from other code. Almost all (but not completely
all) Perl code uses regular expressions, so only rarely will this small
amount of initialization be performed when it currently isn't.

Rmv PL_Posix_ptrs
Previous commits in this series have removed all uses of this global
array. This completely removes it.
Since it is a global, consideration need be given to possible uses of it
outside the core. It has never been externally documented, and is an
opaque structure whose internals have changed with every release. The
functions used to access it are almost all static to regcomp.c; those
few that aren't have been hidden from all but the few .c files that need
to have access to them, via #if's.

regcomp.c: Rmv remaining uses of PL_Posix_ptrs
Previous commits have removed all but a few uses of PL_Posix_ptrs. This
removes the rest. ASCII is the same whether over all code points, or
just the ASCII range, so we can substitute the version for all code
points. There is an extra intersection introduced by this commit during
the construction of a synthetic start class under /a and /aa, but the
performance hit should be negligible.

regcomp.c: Collapse two branches.
Previous commits in this series have removed the need to special case
[:ascii:]. This commit removes the special casing. There is a slight
performance penalty if this is the only POSIX class in the bracketed
class, and is being compiled under /a or /aa: An extra intersection will
be performed. Since this is regex compilation, this should be
unnoticeable.

XXX finish regcomp.c: Trade a little time for simplicity
Perl traditionally has chosen time when there is a space tradeoff. This
commit goes the other way, but the reason isn't space, it is for
making the code simpler.
Perl currently has two sets of inversion lists for the POSIX classes
built in. One set is for the entire Unicode range; the other for just
the ASCII range. This latter set could be derived from the larger one
at run time by doing an intersection with ASCII.

Keep temp separate list of posix classes and complements
In building up the list of code points that are matched by a bracketed
character class, there can be both posix classes and complemented posix
classes, like [\s\W]. By keeping each type in a separate list, we can
simplify code in later commits.

Keep temp separate list of foldable characters
When populating what a bracketed character class should match, it turns
out that if we keep a separate list of code points whose folds may have
to be added, we can simplify the code. This commit just adds the new
list. Future commits will do the simplification.

Compile in list of foldable code points
When constructing what matches code points under /i, Perl uses an
inversion list of all the possible code points that participate in
folds. This number is relatively few compared to the possible universe
of code points, as most of the world's scripts aren't cased, and many
characters in the scripts that do fold aren't foldable (such as
punctuation). Prior to this commit, the list for the above-Latin1 code
points was read-in from disk if and only if needed. This commit causes
the list to be added to read-only data in a C header, trading a little
space in Perl's text segment for speed at execution. This will enable
ripping out some code in this and future commits (offsetting the space
used by this one).

regcomp.c: Rmv code for delayed 'til runtime POSIX defns
The previous commit made compile-time inversion lists available for all
POSIX classes, not just some.. Therefore the code that deals with not
having them available until runtime can be removed. This commit does
the largest chunk of this code, used when a POSIX class is used within a
bracketed character class.

Compile in all POSIX class inversion lists
This changes charclass_invlists.h to have the complete definitions for
all the POSIX classes, like \w and [:alpha:]. Thus these won't have to
be loaded off disk at run-time.
Taking advantage of this will be done in stages in future commits
