H A Dops_sse.hdiff a64eee3ab402469b536db9aeb259097b84d31d0f Tue Sep 20 10:48:14 CDT 2022 Paolo Bonzini <pbonzini@redhat.com> target/i386: clarify (un)signedness of immediates from 0F3Ah opcodes

Three-byte opcodes from the 0F3Ah area all have an immediate byte which
is usually unsigned. Clarify in the helper code that it is unsigned;
the new decoder treats immediates as signed by default, and seeing
an intN_t in the prototype might give the wrong impression that one
can use decode->immediate directly.
