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.

if both types are named, they must be
the same type (arising from the same
declaration).

replace "shape error across CALL" with more information.
x.go:7: not enough arguments to CALL
a int, b int
int
x.go:10: assignment count mismatch: 3 = 2

also leave type alone after conversion failure,
for later errors:
bug049.go:6: cannot convert nil constant to string
bug049.go:6: illegal types for operand: EQ
string
nil # this used to be blank

you should be able to convert a pointer to an array to a
slice, you should not be able to convert an array to a slice.
Currently 6g works the other way around.
