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.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.

to catch incorrect code generation, usually due to incorrect
test of immediate size. The test checks a large amount of
encodings in "power of two" boundaries. This test exorcises
a significant amount of code paths that was previously not
tested.
* check/Makefile.am: Add range test to make check target.
* lib/jit_aarch64-cpu.c: Correct wrong address calculation
for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
too large.
* lib/jit_mips-fpu.c: Correct wrong size test to check if
an immediate can be encoded in a float or double store.
* lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
when the offset cannot be encoded, and fallbacks to an
alternate encoding in 2 instructions.

lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
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_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
jit_frame and jit_tramp interfaces, that allow writing
trampoline like calls, where a single dispatcher jit buffer
is written, and later other jit buffers are created, with
the same stack frame layout as the dispatcher. This is the
logic that GNU Smalltalk used in lightning 1.x, and is required
to make a sane port for lighting 2.x.
* jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
and also correct wrong encoding for B4 instructions, that
implement jmpr, as well as correct reverse logic in _jmpr,
that was moving the branch register to the jump register,
and not vice-versa.
Also, if a stack frame is to be assumed, always assume it may
call a function with up to 8 arguments, regardless of the
hint frame argument.
* lib/jit_arm.c: Add a new must_align_p() interface to ensure
function prologs are always aligned. This condition was
previously always true, somewhat by accident, but with
jit_tramp it is not guaranteed.
* jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
required to implement jit_tramp, where a function descriptor
should not be added before a prolog, as jit_tramp means omit
prolog.
* check/lightning.c: Update test driver for the new interfaces.
* check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
a simple test and example of the jit_frame and jit_tramp
usage implementing a simple Fibonacci function using a
simulation of an interpreter stack and how it would handle
state in language specific variables.
* doc/body.texi: Add documentation for jit_frame and
jit_tramp.

lib/jit_x86-x87.c: Review generation of all branch
instructions and always adds the jit_class_nospill
bitfield for temporary registers that cannot be spilled
because the reload would be after a conditional jump; the
patch only adds an extra assertion. These conditions do
not happen on documented lightning usage, but can happen
if one uses the not exported jit_get_reg and jit_unget_reg
calls and cause enough register starvation.
* include/lightning.h, include/lightning/jit_private.h,
lib/lightning.c: Implement the new jit_set_data() interface,
and the new jit_get_data() helper. Like jit_set_code(),
jit_realize() should be called before jit_set_data().
The most common usage should be jit_set_data(JIT_DISABLE_DATA
| JIT_DISABLE_NOTE), to force synthesize any float/double
constant in the stack and not generate any debug information.
* lib/jit_note.c: Minor change to debug note generation as
now it uses an alternate temporary data buffer during constants
and debug generation to accommodate the possibility of the user
setting an alternate data buffer.

lib/jit_s390x-sz.c: Update for several instructions that now

validation on n32 and n64 abis (and/or big endian).
* lib/jit_mips-sz.c: Update for changes in o32.
* lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
validation on Darwin PPC.
* lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
64 bit.
* lib/jit_ia64-fpu.c: Implement untested jit_set_data.
* TODO: Add note to list ports that were not tested for the
new jit_set_data() feature, due to no longer having access
to them.
* check/nodata.c: New file implementing a simple test exercising
several different conditions created by jit_set_data().
* check/check.nodata.sh: New file implementing a wrapper
over the existing *.tst files, that runs all tests without
using a data buffer for constants; only meaningful (and
enabled) on architectures that used to store float/double
constants on a read only data buffer.
* configure.ac, check/Makefile.am: Update for the new test
cases.
* check/lightning.c: Implement the new "-d" option that
sets an internal flag to call jit_set_data() disable
constants and debug, that is, using only a pure code
buffer.
* include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
implementing the new s390x port.
* configure.ac, include/lightning.h,
include/lightning/Makefile.am,
include/lightning/jit_private.h,
lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
Minor adaptation for the new s390x backend.
* check/float.tst: Update for the s390x result of
truncating +Inf to integer.
* check/qalu_mul.tst: Add extra test cases to better test
high word of signed multiplication as the result is
adjust from unsigned multiplication on s390x.
