* include/lightning.h, include/lightning/jit_private.h,
lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
lib/lightning.c: Make jit_ellipsis implementation not
backend specific. It is not intended to handle va_list
like objects at runtime, as jit_arg* and jit_getarg*
return constant values resolved at parse time, so, effectively
it is not possible to create printf like jit functions, as
there is no va_start, va_arg, va_end, etc, abstraction. This
limitation should be kept for the sake of making new ports
easier.
* include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
to no longer receive an argument. If receiving an argument, it
should be an ABI specifier, not a boolean if varargs or not,
and add the new jit_ellipsis call, to specify where the
ellipsis is in the C prototype of the function being called.
Note that currently it is not supported to define varargs
functions and it will be ignored if calling jit_ellipsis not
in a prepare/finish* block, but this should be addressed.

check/lightning.c: Update for the change to jit_prepare and
addition of jit_ellipsis.
* check/all.tst, check/lightning.c: Only declare or use 64 bit
interfaces on 64 bit builds.
* check/fib.tst: Use simpler logic to not need preprocessor
conditionals for 32 or 64 bit.
* include/lightning.h: Only declare 64 bit macros on a 64 bit
build. Code using lightning must know about wordsize and the
jit generation limitations, also, this way it generates a
compile time failure, not a runtime assertion.
* include/lightning/jit_x86.h: Correct typo in macro name.

lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
current jit function pointer.
* lib/lightning.c: Move call to the simplify() optimization
to after register liveness is known. Previous code did work
by accident but now with proper test cases the problem was
noticed.
* lib/jit_disasm.c: Always cast bfd_vma to long long when
passing it as printf argument.

New sample input for the new test program, loosely matching
several of the previous test cases.
* check/Makefile.am: New test suite makefile.
* check/check.sh, check/run-test: New wrapper files for the
new test suite.
* check/lightning.c: New file. The main driver of the new test
suite, that compiles to a parser of a very simple assembly like
language, generates jit and executes it.
* check/all.tst: New file. A generic debug and sample test file
with a directive to prevent it from being executed, and useful to
read disassembly of all possible instructions, using a fixed set
of registers.

written from scratch, only by <pcpa@gnu.org>, and have now
copyright assignment to the FSF. This is the core of the new
lightning rework. Previously it was integrated in code with
a garbage collector and several custom types like vectors and
hash tables, so this first code merge with lightning converts
that code into a library extracting only the jit bits, and at
first only for x86_64 GNU/Linux.
* lightning.h, m4/lightning.m4: Removed. These are no longer
required in the new lightning code.
.gitignore, Makefile.am, configure.ac: Update for the new
lightning code.
