Paolo Bonzini 38e65936a8 target/i386: allow MMX instructions with CR4.OSFXSR=0
MMX state is saved/restored by FSAVE/FRSTOR so the instructions are
not illegal opcodes even if CR4.OSFXSR=0.  Make sure that validate_vex
takes into account the prefix and only checks HF_OSFXSR_MASK in the
presence of an SSE instruction.

Fixes: 20581aadec ("target/i386: validate VEX prefixes via the instructions' exception classes", 2022-10-18)
