b2871b727e working on bgen 
- removed smallint optimizations
- lifted raddr from 5c
- add back %R, was used in gc/* causing -g to crash
- changed naddr OREGISTER to emit D_REG instead of D_OREG

d330c712c1 Getenv: almost no one wants the error, so make it return a string that may be empty. 
Getenverror is the new name for the old routine that returns an error too.

a0bcaf4c00 Change os.Error convention: 
echo back context of call in error if likely to be useful.

For example, if os.Open("/etc/passwd", os.O_RDONLY)
fails with syscall.EPERM, it returns as the os.Error

	&PathError{
		Op: "open",
		Path: "/etc/passwd"
		Error: os.EPERM
	}

which formats as

	open /etc/passwd: permission denied

Not converted:

	datafmt
	go/...
	google/...
	regexp
	tabwriter
	template

1ac2cfc720 grab bag of changes aimed at getting stack splitting to work: 
- morestack support for 5l and arm runtime
- argsize support in 5c, 5l, ar and nm. assembly code from 5a
  will break in interesting ways unless NOSPLIT is specified
- explicit cond execution constants
- fix 5l output to use %d instead of %ld so that negative
  values show.
- added a lot of code to arm/asm.s. runtime entry code almost
  working currently aborts at gogo not implemented
