Actual results:
Thunderbird freezes after a few seconds (UI stops responding and/or updating)

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

This patch should fix the freezes.
