    X87: [builtins] Add receiver to builtin exit frames. · e043dcb5

      original commit message:
      Stack trace generation requires access to the receiver; and while the
      receiver is already on the stack, we cannot determine its position
      during stack trace generation (it's stored in argv[0], and argc is only
      stored in a callee-saved register).
    
      This patch grants access to the receiver by pushing argc onto builtin
      exit frames as an extra argument. Compared to simply pushing the
      receiver, this requires an additional dereference during stack trace
      generation, but one fewer during builtin calls.
