Bug 1098070 - Remove trailing whitespace from nsCCUncollectableMarker.cpp. r=smaug
Bug 868139 - Don't redo unmarking work in nsGlobalWindow::CanSkip if we already did it. r=smaug

This causes quadratic behavior in forgetSkippable when there are many timeouts.

To avoid this, we mark the CC generation of the last time we ran CanSkip on the window,
and don't do it again if it hasn't changed.
Bug 1018397 - Start an ICC timer even if ICC is globally disabled. r=smaug
