Subject: Support hint <imm>, and fix hint disassembly.

This allows users to use custom hints without resorting to an undefined
static_cast.

Also, fix disassembly of hints:
  - Add several named hints to the disassembler, so they can be properly
    disassembled.
  - Properly disassemble unnamed hints.
