Remove the 's' DataLayout specification
During the years there have been some attempts at figuring out how to align byval arguments. A look at the commit log suggests that they were * Use the ABI alignment. * When that was not sufficient for x86-64, I added the 's' specification to DataLayout. * When that was not sufficient Evan added the virtual getByValTypeAlignment. * When even that was not sufficient, we just got the FE to add the alignment to the byval. This patch is just a simple cleanup that removes my first attempt at fixing the problem. I also added an AArch64 implementation of getByValTypeAlignment to make sure this patch is a nop. I also left the 's' parsing for backward compatibility. I will send a short email to llvmdev about the change for anyone maintaining an out of tree target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198287 91177308-0d34-0410-b5e6-96231b3b80d8
