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: Extend tests to validate jit_callee_save_p
does not cause an assertion on valid arguments, and test
extra registers defined on some backends.
* configure.ac: Do not ignore environment CFLAGS when
checking if need to test runtime configurable options,
like use x87 when sse2 is available, arm instruction set
instead of thumb, etc.
* include/lightning/jit_arm.h: Correct wrong jit_f macro
definition.
* include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
Correct wrong jit_r macro definition.
* lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
reserved stack space for integer to/from float conversion.
The stack space was also changed to ensure it is 8 bytes
aligned. Also, for Solaris x86 in 32 bit mode, an alternate
truncr_d was implemented because for some reason it is
failing with SIGILL if using the "fisttpl" instructions,
that must be available on p6 or newer, but for the sake of
making all tests pass, implement a 486 or newer sequence
if "sun" is defined.
* include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
lib/jit_ia64-fpu.c, lib/jit_ia64.c:
Relocate JIT_Rn registers to the local registers, as, like
float registers, div/rem and sqrt are implemented as function
calls, and may overwrite non saved scratch registers.
Change patch_at to receive a jit_code_t instead of a
jit_node_t, so that it is easier to "inline" patches when
some instruction requires complex code to implement, e.g.
uneq and ltgt.
Correct arguments to FMA and FMA like instructions that,
due to a cut&paste error were passing the wrong argument
to the related F- implementation function.
Rewrite ltgt to return the proper result if one (or both)
of the arguments is unordered.

lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
lib/lightning.c: Rework code to detect need of a "stop" to
also handle predicates, as if a predicate is written, it
cannot be read in the same instruction group.
Use a single jit_regset_t variable for all registers when
checking need for a stop (increment value by 128 for
float registers).
Correct wrong "subi" implementation, as the code executed
is r0=im-r1, not r0=r1-im.
Use standard lightning 6 fpr registers, and rework to
use callee save float registers, that may be spill/reloaded
in prolog/epilog. This is required because some jit
instructions implementations need to call functions; currently
integer div/mod and float sqrt, what may change the value of
scratch float registers.
Rework point of "sync" of branches that need to return a
patch'able address, because the need for a "stop" before a
predicate read causes all branches to be the instruction
in slot 0, as there is no template to "stop" and branch
in the same instruction "bundle".
* include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
the basic infrastructure of an Itanium port. The code
compiles and can generate jit for basic hello world like
functions.
* check/lightning.c, configure.ac, include/lightning.h,
include/lightning/Makefile.am, include/lightning/jit_private.h,
lib/Makefile.am, lib/lightning.c: Update for the Itanium
port.
* lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
make the jit_carry register local to the jit_state_t.
This matches code reviewed in the Itanium port, that
should use the same base logic to handle carry/borrow.
