B-C-1.53 - Perl compiler

Changes for version 1.53 - 2015-12-06

added 5.22 support, some cperl optimizations and fixed most remaining 5.14 issues. Bytecode broken upstream with 5.22.0
Bytecode (1.17): removed lastsib bit for 5.21.2-5.21.10, support only moresib op Add ops for padl, padn, padnl, unop_aux and methop needed for 5.22 ByteLoader was broken upstream with 5.22. You need to build a perl with `perlall build --patches-Compiler 5.22.0` or use cperl5.22.2. Added a probe, set $B::C::Flags::have_byteloader
Disassembler (1.13), Assembler (1.13): support PADNAME and PADNAMELIST for 5.22
C: fix B::PMOP::precomp for UTF8 (#333, #338, GH#50) Add 5.22 support with a new unop_aux (multideref) section, methop support, new support for PADNAME and PADNAMELIST objects. Fix upstream B::UNOP_AUX::aux_list bug with threads. Use our own method which returns the PADOFFSET, not the SV. (#341) Removed B::Section which used base. (toddr) Re-add PL_sv_objcount on cperl Fixed XSUB CONSTSUB alias (44,45,... PR #228) (atoomic) and anonymous CVs for 5.22 (#246, #305) Proper utf8 support for gv_fetchpv, gv_stashpv and cv_get, cache gv_stashpv calls. Fix 5.22 for empty hash keys, share_hek("") (272, GH#249) Fixed refcounts for shared hek's, fixing the notorious unshare_hek assertions since 5.10 (GH #251, #255). See 1.06: "Had to disable -O1 -fcog (pv_copy_on_grow) on 5.10 and higher until I find out how to fool S_unshare_hek_or_pvn. This fixes all C -O1 and -O2 tests. Warn about this." Fix Inf/NaN support for C (GH#287) Fix handling of READONLY hashes in 5.22, i.e. use feature (GH#250) Support custom op Devel_Peek_Dump, added with 5.20 (GH#274) Defer regex compilation to new init1 for SWASHNEW (GH#273) Support unicode labels (upstream B bug) (GH#318) Skip unneeded init-time lexwarn checks, support optimized cperl PERL_SUPPORT_STATIC_COP (cperl #70) Fixed overload stringify broken since 5.18 (GH #219) by adding a mro_isa_changed_in() to the overloaded stash. Support multiple stash ENAMES, needed since 5.14 (GH #331) This fixed many old 5.14 limitations. (Added to our version of B) Support %^H, storing the hints_hash (features, pragmas) (GH#220) This fixed many old 5.14 limitations. Improve MATCH once (m??) handling with reset, find PMOP from the Regexp dynamically (GH#252) Bump refcounts of dynamic get_cv refs (#293). Fixes Coro in global destruction. Skip more XS defined POSIX constants: all that start with 'M' (GH#335, #345) One more "Eval-group not allowed at runtime" fix (GH#137, GH#346)
CC (1.16_01): Encode unicode labels (GH#318)
Stackobj (1.12_01): fix Inf/NaN support for CC (GH#287)
t/CORE: versioned the core tests and moved to a external submodule perl11/p5-coretests on github. (GH#332)
