Log message:
	mark all non-bitfield fields as addressable
	This was part of a not yet very successful attempt at
	dealing with configure -enable-checking, and its flagging
	of our heavy use of bitfield refs.
	Hopefully we get something that isn't as bad as volatile.
	Hopefully we can remove this addressability actually,
	though I'll probably add more first (objects, arrays, etc.)
	
	Lots of cosmetic/cleanup.
	o => offset
	n => name
	len, n_len => name_length
	val => value
	p => proc
	l => label
	a, b, c, aren't terrible identifers, but l is particularly
	onerous due to resembles to 1
	t => type
	more to do here
	some functions have v and val, can't both be value
	tree *f => out_f, and use local f to avoid repeated derefs
	tree *v => out_v
	consolidate all tracing options
	There is just one variable now, option_trace_all, and
	all the options increment it. Almost all of the tracing
	is at level 1, a little is at 2.
	
	call one_gap/m3_gap unconditionally and have it do the check
	
	some missing spaces on function calls
	(really I'd just as soon remove them all, but they are
	fairly consistently present, so I'm following that style)
	
	remove the list of optimizations to possibly disable
	if need be, regain them from where they came
	
	tweak the options a little less; ongoing experimentation
	to reduce them, but some of them require a lot of
	debugging and fixing
	
	work in progress to synthesize field accesses on loads/stores
