as a reminder, the old conversion
was that you could write

	var arr [10]byte;
	var slice []byte;
	slice = arr;

but now you have to write

	slice = &arr;

the change eliminates an implicit &, so that
the only implicit &s left are in the . operator
and in string(arr).

also, removed utf8.EncodeRuneToString
in favor of string(rune).

6g generates for functions: expect the keyword "func".  The
older reflection syntax, without the "func", is still
recognized for simplicity in parsing interface reflection
strings.
