mem: Signal the local monitor when clearing the global monitor
ARM systems require the coordination of the global and local monitors. When the system is run without caches the global monitor is implemented in the abstract memory object. This change adds a callback from the abstract memory that notifies the local monitor when the global monitor is cleared.
Additionally, for ARM systems the local monitor signals the event register and wakes the thread context up. Subsequent wait-for-event (WFE) instructions will be immediately signaled.

cpu: Add CPU support for generatig wake up events when LLSC adresses are snooped.
This patch add support for generating wake-up events in the CPU when an address that is currently in the exclusive state is hit by a snoop. This mechanism is required for ARMv8 multi-processor support.

o3: Fix issue with LLSC ordering and speculation
This patch unlocks the cpu-local monitor when the CPU sees a snoop to a locked address. Previously we relied on the cache to handle the locking for us, however some users on the gem5 mailing list reported a case where the cpu speculatively executes a ll operation after a pending sc operation in the pipeline and that makes the cache monitor valid. This should handle that case by invaliding the local monitor.

Make commenting on close namespace brackets consistent.
Ran all the source files through 'perl -pi' with this script:
s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|;
Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.

POWER: Add support for the Power ISA
This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.
