[AArch64][Patch 2/5] Add Statistical Profiling Extension system registers.
The Statistical Profile extension included in the ARMv8.2 architecture
adds a number of system registers. This patch adds the registers to
binutils, making them available when the architecture extension
"+profile" is enabled.
