Is there an advantage to having a larger buffer?

[shuffle2]

Both changes are for speed: the buffer will now be properly aligned for simd, and zlib-ng can take advantage of that and the larger buffer size to use faster code.

I’m getting this error after the change. All games on Metal, M1..

01:09:319 Common/Arm64Emitter.cpp:537 E[JIT]: Warning: An error occurred.

64-bit load/store must use aligned offset: 1892

  Condition: (imm & 0x7) == 0

Ignore and continue?

The changed files in here shouldn’t cause this bug but I tried running with #10808 (previous commit) and it runs fine. 10808 looks like it should be causing the bug. I’ll do more testing.
