Add consistency check on temporaries during a jump
* lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, lib/jit_arm-cpu.c, lib/jit_arm-vfp.c, lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c, lib/jit_s390x.c, lib/jit_sparc-cpu.c, lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: Review generation of all branch instructions and always adds the jit_class_nospill bitfield for temporary registers that cannot be spilled because the reload would be after a conditional jump; the patch only adds an extra assertion. These conditions do not happen on documented lightning usage, but can happen if one uses the not exported jit_get_reg and jit_unget_reg calls and cause enough register starvation.
