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.

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_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.
* include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
* check/float.tst: Add preprocessor for hppa expected
values when converting NaN and +-Inf to an integer.
* check/ldst.inc: Ensure double load/store tests use an
8 byte aligned address by default.
* lib/lightning.c: Correct a bug found during tests in
the new port, where qmul* and qdiv* were not properly
setting one of the result registers as modified in the
function, what would be a problem if the only "write"
usage were the qmul* or qdiv*.
* check/varargs.tst, check/varargs.ok: Add one extra
interleaved integer/double test to validate proper code
generation in the extra case.
* check/lightning.c, configure.ac, include/lightning.h,
include/lightning/Makefile.am,
include/lightning/jit_private.h, lib/Makefile.am,
lib/jit_disasm.c: Update for the hppa port.
