Correct implementation problems on ix86.

* check/all.tst, check/lightning.c: Only declare or use 64 bit interfaces on 64 bit builds. * check/fib.tst: Use simpler logic to not need preprocessor conditionals for 32 or 64 bit. * include/lightning.h: Only declare 64 bit macros on a 64 bit build. Code using lightning must know about wordsize and the jit generation limitations, also, this way it generates a compile time failure, not a runtime assertion. * include/lightning/jit_x86.h: Correct typo in macro name. * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c, lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c, lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get current jit function pointer. * lib/lightning.c: Move call to the simplify() optimization to after register liveness is known. Previous code did work by accident but now with proper test cases the problem was noticed. * lib/jit_disasm.c: Always cast bfd_vma to long long when passing it as printf argument.
