65816: Emulation mode: New instructions should not page wrap

[ReverendGumby]

According to 65C816 Opcodes by Bruce Clark, because these instructions / addressing modes are new (not present on 65*02), they should not page wrap:

• 17.e.json: ORA [d],y
• 57.e.json: EOR [d],y
• 77.e.json: ADC [d],y
• 97.e.json: STA [d],y
• d4.e.json: PEI

Further, PLB should read from $0200 when S=$FF.

• ab.e.json: PLB

A patch is attached.
