    YJIT: Detect and reject `send(:alias_for_send, :foo)`

    Previously, YJIT failed to put the stack into the correct shape when
    `BasicObject#send` calls an alias method for the send method itself.
    This can manifest as strange `NoMethodError`s in the final non-send
    receiver, as [seen][1] with the kt-paperclip gem. I also found a case
    where it makes YJIT fail the stack size assertion while compiling
    `leave`.

    YJIT's `BasicObject#__send__` implementation already rejects sends to
    `send`, but didn't detect sends to aliases of `send`. Adjust the
    detection and reject these cases.

    Fixes [Bug #19464]
