* tree-loop-linear.c (linear_transform_loops): Don't test
perfect_nest_p.
Call rewrite_into_loop_closed_ssa only when something changed.
* lambda.h (gcc_loopnest_to_lambda_loopnest): Update declaration.
* lambda-code.c (can_convert_to_perfect_nest): Declared.
(gcc_loopnest_to_lambda_loopnest): Removed need_perfect_nest parameter.
Test for perfect_nest_p here. Fix formating.
(replace_uses_equiv_to_x_with_y): Fix formating.
(stmt_uses_op): Removed.
(can_convert_to_perfect_nest): Removed loopivs parameter.
Complete the test by checking the scalar dependences.
(perfect_nestify): Remove the test for can_convert_to_perfect_nest.
Fix formating. Don't copy statements in the inner loop: move them to
the inner loop header.
