	cm3/m3-sys/m3back/src/: M3C.m3 

Log message:
	now that imports are earlier, remove ReportFault hack that caused
	us to use #ifdef to list all 64bit targets; much better!
	
	work in progress: only output helper functions that are used
	this helps gcc -Wall
	this is made easy by the multi-pass infrastructure
	
	remove our zero initialization of everything
	I think frontend generates it anyway
	
	optimize div and mod when input signs are known to match
