parts/inc/misc: Backport some isFOO_LC macros

A few of this class of macros did not go back very far.  This makes a
reasonable attempt to get things right, but very early versions may have
some wrong answers, but unlikely.

This was complicated by the fact that isascii() and isblank() may not be
available on a given platform.  So this just uses the plain non-locale
version for those very early Perl versions.

I didn't add tests.  It is hard to portably test locales.  The next
commits will backport functions that call these and do have tests.

Reimplement tr/// without swashes

This large commit removes the last use of swashes from core.

It replaces swashes by inversion maps.  This data structure is already
in use for some Unicode properties, such as case changing.

The inversion map data structure leads to straight forward
implementation code, so I collapsed the two doop.c routines
do_trans_complex_utf8() and do_trans_simple_utf8() into one.  A few
conditionals could be avoided in the loop if this function were split so
that one version didn't have to test for, e.g., squashing, but I suspect
these are in the noise in the loop, which has to deal with UTF-8
conversions.  This should be faster than the previous implementation
anyway.  I measured the differences some releases back, and inversion
maps were faster than the equivalent swash for up to 512 or 1024
different ranges.  These numbers are unlikely to be exceeded in tr///
except possibly in machine-generated ones.

Inversion maps are capable of handling both UTF-8 and non-UTF-8 cases,
but I left in the existing non-UTF-8 implementation, which uses tables,
because I suspect it is faster.  This means that there is extra code,
purely for runtime performance.

An inversion map is always created from the input, and then if the table
implementation is to be used, the table is easily derived from the map.
Prior to this commit, the table implementation was used in certain edge
cases involving code points above 255.  Those cases are now handled by
the inversion map implementation, because it would have taken extra code
to detect them, and I didn't think it was worth it.  That could be
changed if I am wrong.

Creating an inversion map for all inputs essentially normalizes them,
and then the same logic is usable for all.  This fixes some false
negatives in the previous implementation.  It also allows for detecting
if the actual transliteration can be done in place.  Previously, the
code mostly punted on that detection for the UTF-8 case.

This also allows for accurate counting of the lengths of the two sides,
fixing some longstanding TODO warning tests.

A new flag is created, OPpTRANS_CAN_FORCE_UTF8, when the tr/// has a
below 256 character resolving to one that requires UTF-8.  If this isn't
set, the code knows that a non-UTF-8 input won't become UTF-8 in the
process, and so can take short cuts.  The bit representing this flag is
the same as OPpTRANS_FROM_UTF, which is no longer used.  That name is
left in so that the dozen-ish modules in cpan that refer to it can still
compile.  AFAICT none of them actually use the flag, as well they
shouldn't since it is private to the core.

Inversion maps are ideally suited for tr/// implementations.  An issue
with them in general is that for some pathological data, they can become
fragmented requiring more space than you would expect, to represent the
underlying data.  However, the typical tr/// would not have this issue,
requiring only very short inversion maps to represent; in some cases
shorter than the table implementation.

Inversion maps are also easier to deparse than swashes.  A deparse TODO
was also fixed by this commit, and the code to deparse UTF-8 inputs is
simplified.

One could implement specialized data structures for specific types of
inputs.  For example, a common tr/// form is a single range, like
tr/A-Z/a-z/.  That could be implemented without a table and be quite
fast.  An intermediate step would be to use the inversion map
implementation always when the transliteration is a single range, and
then special case length=1 maps at execution time.
