Implement get_arch_regstr() for SH so that, given a DWARF register number, the
corresponding symbolic name of that register can be looked up.

This patch adds mappings from DWARF register numbers to the register
names used by the ARM `Regs and Stack Access API'.

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").

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.
