emaste be41ee72e0 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.
