* 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_aarch64-sz.c, lib/jit_aarch64.c,
lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
lib/jit_x86.c: Update for new synthesized IR code sequences.

lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.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_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
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_sparc-sz.c, lib/jit_sparc.c: Prepare for the
new jit_va_* interfaces. Not yet implemented, and will
cause an assertion if used.
* check/va_list.tst: Simple early test case, that works
on x86_64, x32, ix86, cygwin, and cygwin64.

lib/jit_sparc-cpu.c, lib/jit_sparc.c,
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.
* doc/body.texi: Add documentation of the new
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.

lib/jit_x86.c: Add the new jit_arg_register_p predicate.
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.
* check/Makefile.am: Update for new test case.

lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
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.

lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
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.
