Ting-Yu Lin 977a6275d1 Bug 1582224 - Split SIDEWAYS bit in WritingMode. r=jfkthame,emilio ... Currently, there's no way to tell whether the SIDEWAYS bit is set from `writing-mode:sideways-*` or `writing-mode:vertical-*; text-orientation:sideways;`. To be able to tell them apart, split SIDEWAYS bits into VERTICAL_SIDEWAYS and TEXT_SIDEWAYS. This is needed by my proposed solution in bug 1102175. Also, provide convenience methods related to sideways writing-mode, and replace obscure checks in the codebase. Note that we don't have the use cases to distinguish vertical-rl from sideways-rl in layout, but for the completeness, IsSidewaysLR() is still defined.
