Andy Balholm 0ce1ffc49d regexp/syntax: append patchLists in constant time ... By keeping a tail pointer, we can append to a patchList in constant time, rather than in time proportional to the length of the list. This gets rid of the quadratic compile times we were seeing for long series of alternations. This is basically the same change as e9d517989f. Fixes #39542.
