[PATCH 00/21] RISC-V: add gcc support for Scalar Cryptography v1.0.0-rc5

[siyu@isrc.iscas.ac.cn]

From: SiYu Wu <siyu@isrc.iscas.ac.cn>

This patch add gcc backend support for RISC-V Scalar Cryptography 
Extension (k-ext), including machine description, builtins defines and 
testcases for each k-ext's subset.

A note about Zbkx: The Zbkx should be implemented in bitmanip's Zbp, but 
since zbp is not included in the bitmanip spec v1.0, and crypto's v1.0 
release will earlier than bitmanip's next release, so for now we 
implementing it here.

  [crypto]: add machine description for Zknd and Zkne
  [crypto]: add builtins for Zknd and Zkne
  [crypto]: add testcases for Zknd and Zkne

  [crypto]: add machine description for Zksed
  [crypto]: add builtins for Zksed
  [crypto]: add testcases for Zksed
  [crypto]: add machine description for Zksh
  [crypto]: add builtins for Zksh

  [crypto]: add option defines for Zbkb, Zbkc and Zbkx
  [crypto]: add implied defines of Zk, Zkn and Zks
  change z* subset assert to allow "zk"
  [crypto]: add machine description for Zbkx
  [crypto]: add builtins for Zbkx
  [crypto]: add testcases for Zbkx
