Description

[AArch64] Add CPU Cortex-R82

This adds support for -mcpu=cortex-r82. Some more information about this
core can be found here:

One note about the system register: that is a bit of a refactoring because of
small differences between v8.4-A AArch64 and v8-R AArch64.

This is based on patches from Mark Murray and Mikhail Maltsev.
