[debugger] Ensure at least one breakable position per function.

The function literal consists of a list of statements. Each statement
is associated with a statement position including break location. The
only exception to this rule is when the function immediately throws if
scope resolution found an illegal redeclaration. Make sure that we add a
break location for this case as well. The debugger relies on this.
