* check/range.ok, check/range.tst: New test case designed
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.
* check/alu_rsb.ok, check/alu_rsb.tst: New files implementing
tests for jit_rsb*.

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_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_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
lib/jit_s390x-sz.c: Update for several instructions that now
have a different maximum length due to jit_set_data.
* lib/jit_mips-fpu.c: Implement jit_set_data, but missing
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.
* check/lightning.c, configure.ac, include/lightning.h,
lib/lightning.c: Add tests and quirks to build/detect
and/or work on Irix.
* include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
in big endian mips, using the n32 abi.
* lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
jit_sqrtr_{f,d} codes.
* check/all.tst, include/lightning.h, lib/jit_print.c: Change
declaration order and call order in all.tst of {add,sub}c and
{add,sub}x. *c must be called before to set the carry and *x
second to use the carry and keep it set. The wrong call order
was causing all.tst to fail in mips, where a register is
allocated to keep a global carry state.
* include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
argument handling and make the mips backend pass the initial
test cases.
* include/lightning.h, ib/jit_print.c, lib/lightning.c:
Add extra enum values for argument handling functions that
could not be abstracted to the current codes, that is, when
float values need to move from/to gpr from/to fpr. It would
be more tempting to add such primitives, but they would have
wordsize limitations, and it is not expected to add codes
with one gpr argument for 64 bit and two for 32 bit.
* lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
to avoid a runtime exception.
