[PATCH] D66708: [X86] Pass v32i16/v64i8 in zmm registers on KNL target.

[Craig Topper via Phabricator via llvm-commits]

craig.topper updated this revision to Diff 217686.
craig.topper added a comment.

Add an entry to release notes. Add a paranoia command line switch to enable the old behavior. Add test cases for the command line option to avx512-calling-conv.ll
