compiler: Don't generate value reference in range clause if receiver is a sink.
The panic in test/fixedbugs/bug454.go was caused by the generation of an unnecessary var reference when writing a range value into a sink. If the receiving variable is a sink, there's no need to dereference a possible NULL pointer.
Fixes Issue 24.
