is almost certainly wrong. If a character matches [:upper:], its fold
likely won't. Same for [:lower:]. What this means is that a regex of

[perl #116148] Pattern utf8ness sticks around
Perl_re_intuit_start would set, but never unset, the RF_utf8 flag in

the sdeconfd not, that are processed using only intuit, will get the flag

uninline panic branch from POPSTACK
This commit saves machine instructions by preventing inlining, and keeps
the error handling code for an extremely rare panic out of hot code. This
should make the interp smaller and faster.
Perl_error_log is a macro that has a very large expansion on threaded
perls, 4 branches and possibly a call to Perl_PerlIO_stderr. POPSTACK
18 times, by asm, on my non DEBUGGING threaded Win32 32 bit Perl 5.17
-O1 compiled with VC 2003. POPSTACK is also used in some core XS modules,
for example List::Util and PerlIO::encoding. The .text section of
perl517.dll dropped from 0xc05ff bytes of x86 instructions to 0xc00ff
after applying this for me.
Perl_croak_popstack was made contextless to save a push/move instruction
at each caller (less instructions in the instruction cache) and for more
opportunity for the compiler to optimize. Since Perl_croak_popstack is a
noreturn, some compilers may optimize it to just a conditional jump
instruction. VC 2003 32 bit did this inside perl517.dll and from XS
modules using POPSTACK. Perl_croak_popstack measures at 0x48 bytes of
instructions under -O1 for me, so previously, those 0x48 minus the
dTHX overhead would have been sitting in the caller because of macro
expansion.

Deprecate calling isFOO_utf8() with malformed
handy.h has character classification macros to determine if a UTF-8
encoded character is of a given type FOO, such as isALPHA_utf8(), etc.
Code that calls these should have first made sure that the parameter is
legal UTF-8. Prior to this patch, false was silently returned for all
illegal UTF-8. Now, in most instances, a deprecation warning is raised.
This is to catch bugs, and prepare for eventual elimination of this
check, which fails to catch read-off-end-of-buffer malformations anyway.
(One idea would be to leave the check in for DEBUGGING builds.)
The cases where no deprecation warning is raised as a result of this
commit is for the classes where the character does not have to be
converted to a code point for its inclusion to be determined. For
example, if malformed UTF-8 is checked to see if it is ASCII, we only
need to check that it is one of the 128 ASCII characters. If it isn't,
we don't bother to see if it is malformed or not. There are other
cases, as well, such as with isSPACE(), where we check if the UTF-8 is
one of a very finite set, without checking for malformedness.
This commit causes a number of apparent bugs to be shown by the Perl
test suite. These do not cause actual failures.

Merge character class handling revamp topic branch into blead
This sequence of commits cuts down the amount of duplication in handling
character classes (like \w, [:graph:]). There are three principal

handle these classes by just 4 (effectively) distinct ones; 3) deprecate
the functions callable from XS that do character classification. XS
code should instead (if they weren't already) use macros in handy.h to
