Some compressed instructions use immediate bits above the range previously being generated. Some instructions were using more bits than were being generated. Others were skipping LSBs to select higher bits only. Instructions that set the upper limit on immediate bits required: `C.J` / `C.JAL` (imm[11:...]), `C.LQSP` / `C.SQSP` (uimm[9:...]), `C.LUI` (nzimm[17:..]) (no increase required), and `C.ADDI4SPN` (nzuimm[9:...])
