They have also been added to the disassembler and the simulator. Drive-by: emit_prefix is now making sure a trampoline doesn't get emitted in between prefix and suffix. Assembler needs to block it using BlockTrampolinePoolScope. Drive-by: more CHECKs are added to the assembler to make sure immediate values have the correct length.
