[PATCH 24/35] target/i386: reimplement 0x0f 0x3a, add AVX


From: Paolo Bonzini
Subject: [PATCH 24/35] target/i386: reimplement 0x0f 0x3a, add AVX
Date: Thu, 13 Oct 2022 23:46:40 +0200

The more complicated operations here are insertions and extractions.
Otherwise, there are just more entries than usual because the PS/PD/SS/SD
variations are encoded in the opcode rater than in the prefixes.

These three-byte opcodes also include AVX new instructions, whose
implementation in the helpers was originally done by Paul Brook
<paul@nowt.org>.
