sync: prevent (*Map).Range from always escaping
After the change from CL 426074 the Range method on Map always
escape the read variable, leading to an allocation.
Since the compiler doesn't do live-range splitting for local variables we
need to use some hints to only escape in that particular branch.
Fixes #62404
