Between the lowering and flattening passes of the compiler, there are several passes that modify the lowered Go parse tree and as errors are discovered, several nodes transform into error nodes. However, for a higher level node such as a construction expression, the erroneous nodes in the subtrees might not propagate their error. The flatten phase for a node now looks for errors in the subtree and flattens the node into an error node if any are found. Fixes golang/go#11559, golang/go#11536, golang/go#11558.
