Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
header file. These types and definitions are supposed to be
only used internally.
* check/self.c, check/self.ok: New files implementing simple
consistency check assertions. At first validating some macros
that use values from different sources agree.
* check/Makefile.am: Update for the new test case.
* include/lightning.h, lib/lightning.c: Add the new
jit_callee_save_p() call, that is intended to be used when
writing complex code using lightning, so that one does not
need to verify what backend is being used, or have access to
private data, to query if a register is callee save or not;
on several backends the scratch registers are actually callee
save.

include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
include/lightning/jit_x86.h: Add an explicit definition for
JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
This allows one to write code based on "#if defined(JIT_XN)"
and therefore, not need to check what is the current backend
or have access to private data structures. This is particularly
useful when writing virtual machines with several specialized,
global registers.
* lib/jit_ia64.c: Properly flag the callee save general
purpose registers as such, so that jit_callee_save_p() works
as intended.
* check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,

include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
include/lightning/jit_private.h, include/lightning/jit_x86.h:
Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
used in any operations due to frequently having special
constraints (usually JIT_FRET). JIT_FP must be made available
because it must be used as the base register to access stack
space allocated with jit_allocai.
* 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_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
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.

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.
