Ian Munsie fead7960f0 perf probe: Add PowerPC DWARF register number mappings
This adds mappings from the register numbers from DWARF to the
register names used in the PowerPC Regs and Stack Access API.  This
allows perf probe to be used to record variable contents on PowerPC.

This requires the functionality represented by the config symbol
HAVE_REGS_AND_STACK_ACCESS_API in order to function, although it will
compile without it.  That functionality is added for PowerPC in commit
359e4284 ("powerpc: Add kprobe-based event tracer").

Ian Munsie cd932c5939 perf: Move arch specific code into separate arch directory
The perf userspace tool included some architecture specific code to map
registers from the DWARF register number into the names used by the regs
and stack access API.

This moves the architecture specific code out into a separate
arch/x86 directory along with the infrastructure required to use it.
