  commit 678920e58463a27c0878b3d070e18811a294cce8
  Author: Jan Beulich <jbeulich@xxxxxxxx>

      x86emul: fix 3-operand IMUL
      
      While commit 75066cd4ea ("x86emul: fix {,i}mul and {,i}div") indeed did
      as its title says, it broke the 3-operand form by uniformly using AL/AX/
      EAX/RAX as second source operand. Fix this and add tests covering both
      cases.
