Restructure the code under the assumption that there will be HINT consumers other than TCG_LOG_INSTR.
Document the current and near-term allocations of the opcode space:
Move the TCG_LOG_INSTR tests to match rs1 == x0, which is the only form that we have emitted, but we were never ignoring rs1.
Reserve SLTI x0, x31, 0xNNN forms for software's introspective use until (and if) RISC-V upstream defines something for that use case.
SLTI x0, x31, 0xNNN
