For example, consider the following operation:
const instance = new Temporal.PlainDate(2000, 5, 2);
instance.until("-271821-04-19");
The spec would have us enter a loop to compute the difference between
these dates by incrementing an intermediate date one day at a time.
Instead, we can do some math to skip ahead much closer to the desired
date.
Our Temporal implementation is woefully out of date. The spec has been
so vastly rewritten that it is unfortunately not practical to update our
implementation in-place. Even just removing Temporal objects that were
removed from the spec, or updating any of the simpler remaining objects,
has proven to be a mess in previous attempts.
So, this removes our Temporal implementation. AOs used by other specs
are left intact.
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
