Benedikt Meurer a9b6f3f7e6 [inspector][stack-traces] Remove support for "displayName". 
As outlined in the design document linked below, we're removing the
support for the non-standard Function.displayName property for the
purpose of Error.stack and DevTools Inspector stack traces. The
motivation here is that the negative lookup is costly, and we have
Function.name as a standard alternative (configurable since ES6 for
exactly this reason).

I dediced to go with JSFunction::GetDebugName(), since
JSFunction::GetName() was confusing in that it'd only get the "name"
property's value if it's a data property, but not with accessors.
JSFunction::GetDebugName() makes it clear that this is really a debug
helper function and might not give you the "name" property value.
