* 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.
