The next CL will remove the -G flag, effectively hard-coding it to its
current default (-G=3).

When the Defn field of a name node is not an ONAME (for a closure
variable), then it points to a body node of the same function/closure.
Therefore, we should not attempt to substitute it at the time we are
substituting the local variables. Instead, we remember a mapping from the
Defn node to the nodes that reference it, and update the Defn fields of
the copied name nodes at the time that we create the new copy of the
Defn node.
Added some comments to the Defn field of ir.Name.
Moved the Defn (and Outer code, for consistency) from namelist() to
localvar(), since Defn needs to updated for all local variables, not
just those in a closure. Fixed case where .Defn was not being set
properly in noder2 for type switches. Fixed another case where the Defn
field had to be updated during transformSelect() because the Defn node
was being completely changed to a new node.
Fixed some spacing in typeswitch2.go
