function can support dynamic stack realignment. That's a much easier question to answer at instruction selection stage than whether the function actually will have dynamic alignment prologue. This allows the removal of the stack alignment heuristic pass, and improves code quality for cases where the heuristic would result in dynamic alignment code being generated when it was not strictly necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93885 91177308-0d34-0410-b5e6-96231b3b80d8
