Support for ARMv8
Ben Avison authored 
Detail:
  * Filled in CPU tables for publicly documented ARMv8 cores (Cortex-A53,57,72).
  * Recent ARM ARMs (e.g. section B1.9.2 of the ARMv7AR ARM) permit the core to
    take an undefined instruction exception upon encountering even not-taken
    conditional undefined instructions. This option is exercised by the
    Cortex-A53, unlike all ARMv7 cores previously supported by RISC OS. This
    unfortunately trips up a lot of kernel code that adapts to different
    architectures at runtime. These have now all been replaced with branches
    over the affected code on the opposite condition.
  * Fixed bug in HAL_InvalidateCache_ARMvF: for the main body of the loop,
    which was written as though to act on the CLIDR register, r8 actually
    contained the CTR register instead.
