34f76b5de5 1. integer division by a constant done. 
2. moved functions from 6g to gc
for portability to other families.

9346c6d901 make every func literal expression allocate, 
so that == on func means that the
functions originated in the same
execution of a func literal or definition.

before, there was an inconsistency:

	func() {x++} != func() {x++}

but

	func() {} == func() {}

this CL makes the second case != too,
just like

	make(map[int]int) != make(map[int]int)
