when assigning a multifield object
(structs or arrays of structs) they
must not contain any fields that could
not be assigned individually.

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.

editing the firstp list was ineffective,
because follow rebuilds it from the textp list.

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.

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.
