Support for stalled-cycles-frontend and stalled-cycles-backend is
added for e500-based processors.
The following mappings are used:
stalled-cycles-frontend or idle-cycles-frontend:
Com:18 Cycles decode stalled
stalled-cycles-backend or idle-cycles-backend
Com:19 cycles issue stalled

The perf code has grown a lot since it started, and is big enough to
warrant its own subdirectory. For reference it's ~60% bigger than the
oprofile code. It declutters the kernel directory, makes it simpler to
grep for "just perf stuff", and allows us to shorten some filenames.
While we're at it, make it more obvious that we have two implementations
of the core perf logic. One for (roughly) Book3S CPUs, which was the
original implementation, and the other for Freescale embedded CPUs.
