("[PATCH v3 00/66] Unaligned access for user-only")
Important points:
* Support unaligned accesses.
* Drop requirement for 256MB alignment of code_gen_buffer.
* Improvements to tcg_out_movi:
- Have a tb-relative register for mips64, reducing the
code size for most pointers,
- Try a few 3-insn sequences,
- Drop everything else into a constant pool.
