then, is it supposed to be testing?

std: rework zstd for new I/O API

This passes tests but it doesn't provide as big a window size as is
required to decompress larger streams.
The next commit in this branch will work towards that, without
introducing an additional buffer.

std.compress.flate.Lookup: Replace invisible doc comments with top-level doc comments

I think it would be better if this invisible doc comments is top-level
doc comments rather than doc comments. Because it is at the start of a

std: update std.builtin.Type fields to follow naming conventions
...
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938 .
