CPU/CodeCache: Simplify code LUT addressing
...
One more instruction on x86/ARM32, no additional instructions on ARM64.
Worth it so that the application doesn't crash if the game jumps to an
invalid PC. Note that the lower 2 bits are truncated, so an unaligned
jump will round down to the closest instruction. Obviously not correct,
but if a game ends up doing this, it's a lost cause anyway.

CPU/Recompiler: Create block links for self-looping blocks

This way invalidation will rewrite the jump back to the compiler.
Otherwise a SMC block can end up looping itself indefinitely.
