In some cases when HexagonTargetLowering::allowsMemoryAccess returned true, it did not set the "Fast" argument, leaving it uninitialized. [Hexagon] Improve casting of boolean HVX vectors to scalars - Mark memory access for bool vectors as disallowed in target lowering. This will prevent combining bitcasts of bool vectors with stores. - Replace the actual bitcasting code with a faster version. - Handle casting of v16i1 to i16.
