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]
