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.
