Do not decommit memory on PPC
Do not decommit memory on PPC since decommit logic assumes PageSize == ArenaSize. On PPC we have 64K page size, which is not feasible for ArenaSize. Rework of Martin's patch from https://bugzilla.mozilla.org/show_bug.cgi?id=746112
Please apply this patch to xulrunner code. This patch should fix the Firefox freezes.
