Log message:
	gcc -Wall work:
	remove unused variables -- would be nice if frontend didn't produce them..
	remove unused labels -- would be nice if frontend didn't produce them..
	mark a few functions as noreturn functions to quash gcc warnings
	including risky hack of removing exit_proc
	asserting that certain functions only have one..presumably/hopefully
	right before end_procedure..
	small hardcoded list of no_functions..kind of hacky..but compiler
	is in bed with runtime is normal..
	still to do -- warning: comparison is always false due to limited range of data type
	(this isn't gcc -Wall, but gcc default, like comparisons
	of unsigned numbers against 0...)
	
	give in and put some newlines in always so the code is more readable
	but still, no/little indentation
