from x86asm.pl. This removes the parameter from asm_init altogether. See
also upstream's e195c8a256.

We're not using the MASM output, so don't bother maintaining a diff on
it.

We're not using the masm output (and upstream does not even support it).
Reduce unnecessary diff from upstream.

Though this doesn't mean that masm becomes supported, the script is
still provided on don't-ask-in-case-of-doubt-use-nasm basis.

We were building the NASM flavor with MASM which is why it didn't work. Get the
MASM output working: cpuid and cmove are not available in MASM unless the file
declares .686. Also work around MASM rejecting a very long line in SHA-256.

The follow-up change will get the NASM flavor working. We should probably use
that one as it's documented as supported upstream. But let's make this one
functional too.
