flate: Handle invalid block type
...
Fixes `panic: invalid enum value` when the type bits had the u2 value of 3.

flate change bit reader Bits to usize ( #24719 )
...
Don't see why byte returned from specialPeek needs to be shifted by
remaining_needed_bits.
I believe that decision in specialPeek should be done on the number of
the remaining bits not of the content of that bits.
Some test result are changed, but they are now consistent with the
original state as found in:

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 .

flate: option to fill BitReader
...
fill(0) will fill all bytes in bit reader. If bit reader is aligned to
the byte, as it is at the end of the stream this ensures no overshoot
when reading footer. Footer is 4 bytes (zlib) or 8 bytes (gzip). For
zlib we will use 4 bytes BitReader and 8 for gzip. After align and fill
we will read those bytes and leave BitReader empty after that.
