Function declarations were previously permitted by V8 in many locations which no ECMAScript specification allowed; the ECMAScript 2015 spec enumerates a few locations (in blocks, as well as after labels and in conditionals when in sloppy mode). This patch ships the flag to restrict the usage of function declarations to those contexts.
