It's slow & often times out randomly on longtest builders. Not useful.

The index 248 results in the decoder calling reflect.MakeMapWithSize
with a size of 14754407682 - just under 15GB - which ends up in a
runtime out of memory panic after some recent runtime changes on
machines with 8GB of memory.
Until that is fixed in either runtime or gob, skip the troublesome
index.
Updates #24308.

Returns at the end of func bodies where the funcs have no return values

When decoding an invalid typeId the associated *decEngine was not
removed from decoderMap. If the decoder was run again on the same input
a nil *decEngine was found in the map and assumed to be initialized,
resulting in a panic.

As we did with encoding, provide a trivial byte reader for
faster decoding. We can also reduce some of the copying
by doing the allocation all at once using a slightly different
interface from byte buffers.

Bytes buffers have more API and are a little slower. Since appending
is a key part of the path in encode, using a faster implementation
speeds things up measurably.
The couple of positive swings are likely garbage-collection related
since memory allocation looks different in the benchmark now.
I am not concerned by them.
