We are going to add code to all the NEON crypto routines that will turn them into non-leaf functions, so we need to manage the stack frames. To make this less tedious and error prone, add some macros that take the number of callee saved registers to preserve and the extra size to allocate in the stack frame (for locals) and emit the ldp/stp sequences.
