This patch fixes PR36658, "Constant pool entry out of range!" in Thumb1 mode.

In ARMConstantIslands::optimizeThumb2JumpTables() in Thumb1 mode, adjustBBOffsetsAfter() is not calculating postOffset correctly by  properly accounting for the padding that is required for the constant pool that immediately follows the jump table branch  instruction.
