Bug 1299727 - Rename NS_WARN_IF_FALSE as NS_WARNING_ASSERTION. r=erahm. The new name makes the sense of the condition much clearer. E.g. compare: NS_WARN_IF_FALSE(!rv.Failed()); with: NS_WARNING_ASSERTION(!rv.Failed()); The new name also makes it clearer that it only has effect in debug builds, because that's standard for assertions.
