Most of the runtime improvements are hard to quantify or summarize,
but it's worth mentioning some of the substantial improvements in STW
time, and that the scavenger now actually works on ARM64, PPC64, and
MIPS.

New Gophers sometimes misconstrue the advice in the "Generality" section
as "export interfaces instead of implementations" and add needless
interfaces to their code as a result. Down the road, they end up
needing to add methods and either break existing callers or have to
resort to unpleasant hacks (e.g. using "magic method" type-switches).
Weaken the first paragraph of this section to only advise leaving types
unexported when they will never need additional methods.

- Mention that a timeout handler now sends a 200 status code on
encountering an empty response body instead of sending back 0.

Both compilers and also go/types don't permit duplicate types in
type switches; i.e., this spec change is documenting a status quo
that has existed for some time.
Furthermore, duplicate nils are not accepted by gccgo or go/types;
and more recently started causing a compiler error in gc. Permitting
them is inconsistent with the existing status quo.
Rather than making it an implementation restriction (as we have for
expression switches), this is a hard requirement since it was enforced
from the beginning (except for duplicate nils); it is also a well
specified requirement that does not pose a significant burden for
an implementation.
Fixes#15896.

Document the following:
* That the algorithmic changes are still compliant with RFC 1951. I remember
people having questions regarding this issue, and it would be good to re-assure
them that it is still standards compliant.
* io.EOF can now be returned early (c27efce66b)
* Use the term "decompress" when referred to as an action. The term "uncompressed"
or "decompressed" are both valid as ways to represent the current state of the data.
