[PULL 07/13] target/i386: Fix decode of cr8

Posted by Paolo Bonzini 4 years ago

From: Richard Henderson <richard.henderson@linaro.org>

A recent cleanup did not recognize that there are two ways
to encode cr8: one via the LOCK and the other via REX.

Fixes: 7eff2e7c
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/380
