Compiler

cc68 rules for cleaning up booluge/boollt etc
Stamp out compiler JMP for JBRA and make sure it works on as68

See if can remove other changes for typecast now fixed the typecast code
(done assign)

X and fp tracking

Rule to clean up the usual 32bit store where we don't need the result again
something like

	std %1,x
	ldd @sreg
	std %2,x
	ldd %1,x
	; notused D

but more importantly and may need a special rule long stores to array via
putind

	std @tmp
	ldd %1,x
	ldd @sreg
	std %2,x
	ldd @tmp
	; notused D

so we eliminate the std @tmp - will need a compiler marker so we can tell
if it's this use of @tmp.

Libraries

Fill in the many missing blanks for pure 6800 library code

32bit maths needs debug

tosmuleax
tosudiveax		(and signed versions)
tosumodeax
tosdiveax
tosmodeax

Optimize the lib680* shifters to spot by 8,16,24 and do moves.

Teach cc basic options people use even as no-ops (-O -g -s)
[-O can turn on register support or something for now. Proper optimizer
 will make it more relevant, -Os needs to go to compiler in the end]
What to do about cc standard output format ? Use -C 0x100 absolute ?

Can we fix --add-source cc65 option and fix/clean up the others
Take out cc65 machine type support

For Fuzix hook the stack checker into a wrapper for brk/sbrk so it does
real checks. Can we use this for space expansion hooks ?

Fuzix binary format option including tacking on debug data

General count the 1 bits multiply helper
(and maybe general  tool to generate lib code for them)
