Proposal for adding splay_tree_find (to find elements without updating the nodes).

w.r.t, https://gcc.gnu.org/wiki/Speedup_areas where we want to improve the performance of splay trees. The function `splay_tree_node splay_tree_lookup (splay_tree, splay_tree_key);' updates the nodes every time a lookup is done. IIUC, There are places where we call this function in a loop i.e.,
