[PATCH] D74146: [SytemZ] Disable vector ABI when using option -march=arch[8|9|10]

[Kai Nacke via Phabricator via cfe-commits]

Herald added projects: clang, LLVM.
When specifying -march=arch[8|9|10], those CPU types do NOT support the vector 
extension. In this case the vector ABI must be disabled. The generated data 
layout should NOT contain 64-v128.
