Add Support For KIL/JAM opcode

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Launch Metroid (USA)
2. Press enter
3. Choose continue
4. Enter BBBBBB BBBBBB BBBBBB IIIIII

What is the expected output? What do you see instead?
I expect a CPU jam. Instead, BizHawk treats the KIL/JAM as an NOP, which causes 
the game to go back to the title screen.

What version of the product are you using? On what operating system?
BizHawk 1.9.3 on Windows x64

Please provide any additional information below.
Nestopia works correctly.
