Opcode 96 04 E9 9E unimplemented

[dborel]

I'm trying to run Bioshock 1.1 on proton 10.3 with WOW64.

[BOX64] 70238|0x115690c1: Unimplemented 32bits Opcode (96 04 E9 9E) F3 0F BA FD 48 87 ED 0F BD EB 0F BA E5 77 0F
wine: Unhandled illegal instruction at address 115690C1 (thread 0140), starting debugger...

I think that translates to the following. Is it supported by Box64?

XCHG EAX, ESI
ADD AL, 0xE9
SAHF

The missing opcode was F3 0F BA... (the byte between parenthesis are the bytes before the issue, just in case)...

The real iisue f the F3 prefix that is to be ignored there.
Opcode should be supported now.

Ok, I have also added this opcode in the interpreter.
