[PATCH v3 00/16] tcg/mips: Unaligned access and other cleanup

[Richard Henderson <richard.henderson@linaro.org>]

Based-on: <20210818191920.390759-1-richard.henderson@linaro.org>
("[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.
