91395ae689 make gobuild failures more readable. 
1. ar reports names of objects with duplicate text symbols.
2. gobuild only shows first line of error output for each failed command.
3. gobuild ignores files that begin with ascii non-alphanumeric non _.

e81d97ea84 clean up gmove: 
* conversions all in one place.
	* no separate load, store phases;
	  direct memory addressing when possible
	  (this is the x86 after all!).
	  avoids extra registers, extra MOVQs.
	* fixes int32 -> uint64 bug
	  (was zero-extending)

2da5022bcf change representation of interface values. 
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.
