(adding //go:build lines).
Not strictly necessary but will avoid spurious changes
as files are edited.

The marshal method allows the hash's internal state to be serialized and
unmarshaled at a later time, without having the re-write the entire stream
of data that was already written to the hash.

Although a 128-bit digest provides little collision resistance it can be
used as a MAC, as found in the WireGuard protocol.

Having a trailing comma before a space doesn't mean that the next option
will be ANDed rather than ORed. This worked with the standard toolchain
because the filenames prevented the incorrect build constraints for
other platforms from being acted on.

Now that the frame sizes of these functions are correct, the compiler
is detecting that they overflow the NOSPLIT stack. They don't need to
be NOSPLIT, so remove that flag.
This fixes the 1.7 build. The build is not broken at tip because the
stack guard is larger.

Currently blake2s's assembly routines claim they have a zero byte
frame and manually subtract upwards of 704 bytes from the stack
pointer without cooperating with Go's ABI. As a result, these
functions may not grow the stack when necessary, leading to memory
corruption.
Fix this by using the correct stack frame sizes so the generated stack
growth prologue is correct, and aligning the SP up instead of down.
