Log:
  MFC r319718: arm64: add ".arch armv8-a+crc" to allow use of crc instructions
  
  With Clang 5.0 the .arch directive is required, otherwise Clang
  complains "error: instruction requires: crc".
  
  This was reported in D10499 but not added initially, because clang 3.8
  available on a ref machine reported unknown directive.  Clang 4.0 allows
  but does not require the directive.
