Description
Feature or enhancement
Bug description:
AArch64 JIT stencils contain a jump at the end of every micro op:
...
// d4: a8c17bfd ldp x29, x30, [sp], #0x10
// d8: 14000000 b 0xd8 <_JIT_ENTRY+0xd8>
// 00000000000000d8: R_AARCH64_JUMP26 _JIT_CONTINUE
These jumps need to be removed and replaced with no-ops to keep the alignment of 8 bytes.
Also the current padding mechanism needs to be removed as well.
