lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
Correct wrong logic in usage of jit_live in jit_retr. The
problem is that if a temporary is required during epilog,
the return register might be allocated, so, jit_live must always
be used.
* lib/jit_rewind.c: New file implementing generic functions
to "rewind", or rewrite IR code sequences.
* include/lightning.h: Add several new codes, that previously
were a function call, that would synthesize the operation.
Now, there is a code for the operation, and a new flag to
know an operation is synthesized.
* include/lightning/jit_private.h: Add several new macros to
help construct synthesized IR code sequences.
* lib/Makefile.am: Update for lib/jit_rewind.c.
* lib/jit_disasm.c: Update for a small rework on jit_node_t,
so that --enable-devel-disassembler does not need a change
in the layout of jit_node_t.
* lib/jit_names.c: Update for the new codes.
* lib/jit_print.c: Update to print more readable output, and
flag synthesized IR code sequences.

lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,

lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
IR code sequences and correct bugs in the initial varargs
implementation support.

lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
support for the new synthesized IR code sequences. Known
most likely broken right now, and should be corrected once
access to these hosts is available.
* lib/lightning.c: Update for new IR codes, and add support
for not yet existing instructions that change third argument.
* size.c: Change to use different tables for LE and BE PowerPC.
Correct a wrong endif for x32.
* include/lightning.h, include/lightning/jit_private.h,
lib/jit_names.c, lib/lightning.c: Add initial support
for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
jit_va_end interfaces. The jit_va_start call is supposed
to return a va_list compatible pointer, but not yet
decided if it will be "declared" stdarg compatible,
as for now only x86 support has been added (and should
be compatible), but issues may arise on other backends.
* check/lightning.c: Add wrappers to call the new jit_va_*
interfaces.
* lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
jit_va_* for x86.
* lib/jit_x86-sz.c: Add fields, but not yet fully updated,
as this is an intermediate commit.

lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
jit_allocar(offs, size) interface, that receives
two integer registers arguments, allocates space
dynamically in the stack, returns the offset in
the first argument, and uses the second argument
for the size in bytes of the memory to be allocated.
* check/allocar.ok, check/allocar.tst: New files
implementing test cases for the new jit_allocar
interface.
* check/Makefile.am, check/lightning.c: Update for
the new test case and interface.

interface.

lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
--enable-devel-disassembler option, that should be used
during development, or lightning debug. This option
intermixes previous jit_print and jit_disassemble
output, making it easier to visualize what lightning
call was used, and what code was generated.

The predicate is expected to be used to know if an
argument is in a register, what would need special
handling if code that can overwrite non callee save
registers is executed.
* check/carg.c: New test case to check consistency and
expected usage of jit_arg_register_p.

jit_arg_f_reg_p from a public header, and define it only
on port specific files where an integer offset is used
to qualify an argument identifier. Exported code expects
an opaque pointer (but of jit_node_t* type) to "qualify"
an argument identifier.
This patch, and the code review/simplification done during
it also corrected some bugs:
o Inconsistent jit_arg_d value of double argument after 3
integer arguments in arm for jit_functions; tested, C
functions were being properly called.
o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
s390 (32-bit) that happened to not have a proper test
case, as it would only happen for jit functions, and
tested, called C functions had proper arguments.
o Corrected a "last minute" correction that did not go
to the committed version, and would not compile on hppa,
due to bad _jit_putargi_d prototype definition.

Implement jit_putarg*. It works as a mix of jit_getarg*
and jit_pusharg*, in the way that the first argument is
a register or immediate, and the second is a pointer
returned by jit_arg*. The use of the interface is to change
values of arguments to the current jit function.
* check/put.ok, check/put.tst: New test cases exercising
the new jit_putarg* interface.
* check/Makefile.am, check/lightning.c: Update for the
new test case and interface.
* include/lightning.h: Split jit_htonr in the new 3 interfaces
jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
available on 64 bit. The plain/untyped jit_htonr macro call
maps to the wordsize one.

assertion to all code generation "drivers" to ensure
_jitc->regarg is empty or in an expected state, after
translation of a lightning instruction to native code.
This change was a brute force test to find out other cases
of a temporary not being release (like was happening with
_bmsi and _bmci on x86), but no other case was found,
after running make check, with assertions enabled, on all
backends.

was a missing lightning 1.x interface, that on most
backends is synthesized, but on a few backends (hppa and ia64),
it can generate better code as on those there is, or the
only instruction with an immediate is in "rsb" format
(left operand).

lib/jit_x86.c: Implement the new jit_align() call that receive
an argument, that tells the modulo, in bytes, to align the
next instruction. In most backends the only value that makes
a difference is a value that matches sizeof(void*), as all
other values usually are already automatically aligned in
labels, but not guaranteed to be aligned at word size bytes.

lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
target that is not a node. This may lead to hard to
debug code generation, but is a required feature for
certain generators, like the ones that used lightning
1.2x. Note that previously, but not really well
documented, it was instructed to use:
jit_movi(rn, addr); jit_jmpr(rn);
but now, plain:
jit_patch_abs(jit_jmpi(), addr);
should also work.

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.

implementing the new aarch64 port, as a new architecture,
not as an expansion of the existing armv[4-7] port.
* check/lightning.c: Add aarch64 support and a small
change to recognize character constants as immediate
values.
* check/float.tst: Add aarch64 preprocessor conditionals
to select proper expected value when converting [+-]Inf
and NaN to integer.
* include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
