include/lightning/jit_s390x.h, lib/jit_disasm.c,
lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c, lib/jit_s390x-sz.c,
lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
Add support for generating jit for s390 32 bit. This change
also removed %f15 from the list of temporaries fpr registers;
it was not being used, but if were, it would corrupt the
stack frame because the spill address would overwrite grp
offsets.
* include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
New files implementing a lightning Alpha port. Thanks
to Trent Nelson and snakebit.net staff for providing access
to an Alpha system.

include/lightning.h, include/lightning/Makefile.am,
include/lightning/jit_private.h, lib/Makefile.am,
lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
Minor changes to adapt for the new Alpha port.
* include/lightning.h, include/lightning/jit_private.h,
lib/lightning.c: Implement the new jit_set_code() interface,
that allows instructing lightning to use an alternate code
buffer. The new jit_realize() function should be called
before jit_set_code(), and usually call jit_get_code()
to query the amount of bytes expected to be required for
the code.
* lib/jit_size.c: Minor update to have less chances of
miscalculating the code buffer by starting the counter
with the size of the longest instruction instead of zero,
as code emit fails if at any moment less than the longest
instruction bytes are available.
* check/setcode.c: New file implementing some basic tests
of the new jit_set_code() interface.
* check/Makefile.am: Update for newer test case.
* lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
lib/jit_x86-sz.c: New files implementing static tables
with longest known instructions length generated to match
a lightning instruction. These tables should make it easier
to make it very unlikely to ever miscalculate, or by too
much, the size of a code buffer.
* lib/jit_size.c: New file that aids to either collect
jit code size information, or use the information depending
on build options.
* size.c: New helper file that parses input for, and create
an initial jit_$arch-sz.c file, that needs some minor edit
for arches with multiple configurations.
* configure.ac, Makefile.am: Add the new, devel mode only
--enable-devel-get-jit-size configure option, that sets
compile time flags to collect jit code size information,
that will be used as input for the "noinst size program".
* lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,

lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
changes for the --enable-devel-get-jit-size build mode,
as well as the "production build mode" with jit code
size information.
