b682f924d7 don't try interface/structure conversion until 
last resort, because it assumes every call is a
real use of the conversion.

1983121bbb 6g interface changes: 
* allow conversion between nil interface and any type.
	* mark signatures as DUPOK so that multiple .6 can
	  contain sigt.*[]byte and only one gets used.

74e2e087e2 change type names to go live at the name, so that 
type T struct {
		next *T
	}

and

	type T *struct {
		next T
	}

are valid without needing forward declarations.

add "type T struct" syntax for forward struct declarations.

add "type T interface" syntax, but commented out
	(need to fix semicolons first)

5383e28ea0 change string([]byte) to pass array, rather than &a[0], 
to string convert.  if the byte array has length 0,
the computation of &a[0] throws an index bounds error.

for fixed size arrays, this ends up invoking arrays2d
unnecessarily, but it works.

9aad9fef76 make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc. 
these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.

(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)

the longs were rare enough that i don't think
it will cause integration problems.
