Add assertion to check for register allocation leaks

Browse source 
* lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
	lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
	lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
	assertion to all code generation "drivers" to ensure
	_jitc->regarg is empty or in an expected state, after
	translation of a lightning instruction to native code.
	This change was a brute force test to find out other cases
	of a temporary not being release (like was happening with
	_bmsi and _bmci on x86), but no other case was found,
	after running make check, with assertions enabled, on all
	backends.
