Ananth N Mavinakayanahalli 8813ff4960 powerpc/sstep: Check instruction validity against ISA version before emulation
We currently unconditionally try to emulate newer instructions on older
Power versions that could cause issues. Gate it.

Fixes: 350779a29f ("powerpc: Handle most loads and stores in instruction emulation code")
