perf: collisions don't contain reserved names by default#684

The 'collisions' set does NOT contain RESERVED_NAMES; they are combined at runtime when needed. For a large real-world, this results in an order of magnitude reduction in memory usage. I'm not joking: Google Ads v5 uses 2.45 GB before this change and 223 MB after.

There was a problem hiding this comment.
Also contains changes to add slots attributes to Metadata and Address. These are ancillary, optional, and open to negotiation.
In the above scenario, they reduce memory usage from 223 MB to 177 MB. If other people feel that the reduction in readability does not warrant the reduction in memory usage I am absolutely open to dropping that particular commit.
I would personally prefer preserving readability.

Perhaps add a note that this is for memory usage?

Includes other minor memory usage optimizations that collectively shave about 5 MB.
