When searching for an instruction to patch out in the arm64 function boundary trace we search for a store pair with a write back. This instruction is commonly used to store two registers to the stack and update the stack pointer to hold space for more. This works in many cases, however not all functions use this, e.g. when the stack frame is too large. In these cases we may find another instruction of the same type that doesn't store through the stack pointer. Filter these instructions out and assume if we see one we are past the function prologue.
