This is a split patch of D120476 and thanks to myhsu. 'Transformed' means the encoding of an immediate is not the same as its binary representation. For example, the `bl` instruction requires a signed 28-bits integer as its operand and the low 2 bits must be 0. So only the upper 26 bits are needed to get encoded into the instruction. Based on the above reason this kind of immediate needs a customed `EncoderMethod` to get the real value getting encoded into the instruction. Currently these immediate includes: ``` uimm2_plus1 simm14_lsl2 simm16_lsl2 simm21_lsl2 simm26_lsl2 ``` This patch adds those `EncoderMethod`s and revises related .mir test in previous patch.
