Stefan kindly informed me that table.el was slowing down menu
operation considerably depending on buffer contents. The attached
patch corrects this problem. Thanks Stefan.

* textmodes/table.el (table--line-column-position): New idiom.
(table--row-column-insertion-point-p): New function to test
validity of row and column insertion operation at a location.
(table-global-menu, table-cell-menu): Use above functions for
deterministic test operation.
(table--editable-cell-p): Behave in deterministic fashion.
