	cm3/m3-sys/m3back/src/: M3x86.m3 Stackx86.m3 

Log message:
	further narrow down extract to what m3front uses
	and we can therefore test
	=> sign_extend requires constant m and constant n
	(I'm thinking I should see if the coverage stuff works..
	and if not fix it..)
	
	stack should handle all 32bit cases inline
	leaving the function calls only for some 64bit cases (for now)
	
	something is fishy here for 64bit + sign extension + non constant m/n
	will resolve shortly
	(for now I'm leaving 64bit extract + sign extend + non constant m/n)
	
	some newlines for readability
