a4754a9ae9 [snapshot][arm64] rename CPU context pstate to spsr
* upon exception, the process state ("pstate") is stored in the saved
process status register ("spsr") so the register we are manipulating is
really just the SPSR
* https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/100878/latest/the-saved-process-status-register
