    In reload, after doing register allocation, we do, in "reload()":

    That mutates the instruction in place, with the possible result that
    it is no longer recognizable.

    Who is supposed to be responsible for making the instruction
    recognizable again?

Reload itself.  The insn won't match its constraints.
