We have a couple of ways to designate spec notes and (our) developer
notes in comments, but we never really settled on a single approach. As
a result, we have a bit of a mixed bag of note comments on our hands.
To the extent that I could find them, I changed developer notes to
`// NB: ...` and changed spec notes to `// NOTE: ...`. The rationale for
this is that in most web specs, notes are prefixed by `NOTE: ...` so
this makes it easier to copy paste verbatim. The choice for `NB: ...` is
pretty arbitrary, but it makes it stand out from the regular spec notes
and it was already in wide use in our codebase.
Before this change, we were going through the chain of base classes for
each IDL interface object and having them set the prototype to their
prototype.
Instead of doing that, reorder things so that we set the right prototype
immediately in Foo::initialize(), and then don't bother in all the base
class overrides.
This knocks off a ~1% profile item on Speedometer 3.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
The main motivation behind this is to remove JS specifics of the Realm
from the implementation of the Heap.
As a side effect of this change, this is a bit nicer to read than the
previous approach, and in my opinion, also makes it a little more clear
that this method is specific to a JavaScript Realm.
