Changes since v5:
- fix use of same register for destination and source in SHA-512 code
- use correct free() function in SHA-3 code
- drop helper for sm3ss1 in SM3 code
- include fixed version of SM4 (correct # of iterations)
- enable SM4 in user mode emulator

Changes since v4:
- restructure code changes to make it easier on the reviewer
- add Peter's R-b to #4

Changes since v3:
- don't bother with helpers for the SHA3 instructions: they are simple enough
  to be emitted as TCG ops directly
- rebase onto Richard's pending SVE work

Changes since v2:
- fix thinko in big-endian aware handling of 64-bit quantities: this is not
  needed given that the NEON registers are represented as arrays of uint64_t
  so they always appear in the correct order.
- add support for SM3 instructions (Chinese SHA derivative)

Changes since v1:
- update SHA512 patch to adhere more closely to the existing style, and to
  the way the instruction encodings are classified in the ARM ARM (#1)
- add patch implementing the new SHA3 instructions EOR3/RAX1/XAR/BCAX (#2)
- enable support for these instructions in user mode emulation (#3)

Ard Biesheuvel (5):
  target/arm: implement SHA-512 instructions
  target/arm: implement SHA-3 instructions
  target/arm: implement SM3 instructions
  target/arm: implement SM4 instructions
  target/arm: enable user-mode SHA-3, SM3, SM4 and SHA-512 instruction
    support

Thanks -- this version passes all my tests and I've put it into
target-arm.next.
