re PR middle-end/50907 (EDGE_CROSSING incorrectly set across same section with -freorder-blocks-and-partition -fPIC -fprofile-use)
PR middle-end/50907
* function.c (convert_jumps_to_returns): When redirecting an edge
succ to EXIT_BLOCK_PTR, clear EDGE_CROSSING flag.
* gcc.dg/tree-prof/pr50907.c: New test.
