    New /s modifier for the disassemble command.

    The "source centric" /m option to the disassemble command is often
    unhelpful, e.g., in the presence of optimized code.
    This patch adds a /s modifier that is better.
    For one, /m only prints instructions from the originating source file,
    leaving out instructions from e.g., inlined functions from other files.
