[PATCH] Loop split upon semi-invariant condition (PR tree-optimization/89134)

This patch is composed to implement a loop transformation on one of its conditional statements, which we call it semi-invariant, in that its computation is impacted in only one of its branches. Suppose a loop as: void f (std::map m) { for (auto it = m.begin (); it != m.end ();
