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.

store only the original import path string (+ .a)

was copying a bit too much about t into n,
like whether the signature was queued to be printed.
(bug reported by anton)
was also editing t, meaning you could do
type T int;
func (p int) Meth() { }

this avoids problems people have run into with
multiple closures in the same package.
when preparing filename, only cut off .go, not .anything.
this fixes a bug tgs ran into with foo.pb.go and foo.go
in the same package.
also turn bad identifier chars from filename into
underscores: a-b.pb.go => a_b_pb

(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.
