I'm looking for a way to get all the caller-saved registers (both the
register and the stack slot at which it was saved) for a given function
call site in the backend. What's the best way to grab this information?
Is it possible to get this information if I have the MachineInstr of the
function call? I'm currently targeting the AArch64 & X86 backends.
