* 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_aarch64.h, include/lightning/jit_arm.h, include/lightning/jit_hppa.h, include/lightning/jit_mips.h, include/lightning/jit_ppc.h, include/lightning/jit_sparc.h, 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.
