b2871b727e working on bgen 
- removed smallint optimizations
- lifted raddr from 5c
- add back %R, was used in gc/* causing -g to crash

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

    unsigned conversions out of the native signed
    ones, 8g turns overflow/underflow into zero.
    the spec does not say what should happen.

  * many tiny bug fixes.  can run a large number

  * struggling with byte register allocation

2da5022bcf change representation of interface values. 
this is not a user-visible change.

before, all interface values were

	struct Itype {
		Sigt *type;
		Sigi *inter;
		void *method[n];
	}

	struct Iface {
		void *addr;
		Itype *itype;
	}

the itype is basically a vtable, but it's unnecessary
if the static type is interface{ }.
for interface values with static type empty, the
new representation is

	struct Eface {
		void *addr;
		Sigt *type;
	}

this complicates the code somewhat, but
it reduces the number of Itypes that
have to be computed and cached,
it opens up opportunities to avoid function
calls in a few common cases,
and it will make it possible to lay out
interface{} values at compile time,
which i think i'll need for the new reflection.

0f153ec6b4 build packages in obj/ subdirectory that mimics $GOROOT/pkg. 
for example, if building in src/lib/container,
objects go in obj/container/, so that 6g -Iobj
will find "container/vector".

install packages in hierarchy in $GOROOT.

this change only updates gobuild.
another change will have to update all
the sources to refer to "container/vector" etc
and regenerate all the Makefiles.

there are some pretty lame functions here
(e.g., Mkdir, Remove, the Getenv("PWD"))
but i will implement better ones in another CL.

* make current 8.out.h and 6.out.h backward compatible
with plan 9's versions.  i had added some constants in
the middle of enums and have now moved them to the end.

99cc2fee81 This is really two changes in one but given interdependencies 
and expected review latency I needed to combine the CLs.

1. Made the 5* toolpath build using the go build
   system. Hooked the subdirectories to clean.bash but added a
   separate make5.bash for now. Minor massage to make the code
   more similar to the current structure of 6c/6a/6l.

2. Change all references from long to int32 in line with
   similar change for the other toolchains.

The end result is that 5c, 5a and 5l can now be compiled and
the executables start up properly. Haven't thrown any input at
them yet.

af678a593d new approach for generating sysimport.c 
(renamed to avoid any conflict with old p4 copies).

this approach doesn't require auto-generating
files also kept in p4, so it should be easier on
go users who don't sync very often.

this approach will be more work for go developers:
builtin.c needs to be copied to builtin.c.boot in p4
as new functions are added.  mkbuiltin does this
for certain $USERs to help us remember.
