[PATCH v2 0/7] target/sparc: Relax some decode for v7/v8

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

Hi Mark,

I noticed a few other places where we probably want to
allow unused bits to be set and ignored for pre-v9.

Changes for v2:
  - Use TRANS() in the STBAR and RDY patches.
  - Apply the same relaxation for RDPSR, RDWIM, RDTBR.
  - Do not report illegal_instruction when unused bits
    are set in the rs2_or_imm field.
