[Alignment] Get DataLayout::StackAlignment as Align
Summary:
Internally it is needed to know if StackAlignment is set but we can
expose it as llvm::Align.
This is patch is part of a series to introduce an Alignment type.
See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2019-July/133851.html
