Log: Remove SPARE_USRSPACE. This constant was used to reserve space at the top of the stack to hold translated system call arguments for non-default ABIs (the "stackgap"). However, none of the compatibility ABIs have used the stackgap in many years and the last use of SPARE_USRSPACE was removed in r355373.
