* tree-ssa-loop-ivcanon.c (tree_estimate_loop_size): Add edge_to_cancel
parameter and use it to estimate code optimized out in the final iteration.
(loop_edge_to_cancel): New function.
(try_unroll_loop_completely): New IRRED_IVALIDATED parameter;
handle unrolling loops with bounds given via max_loop_iteratins;
handle unrolling non-inner loops when code size shrinks;
tidy dump output; when the last iteration loop still stays
as loop in the CFG forcongly redirect the latch to
__builtin_unreachable.
(canonicalize_loop_induction_variables): Add irred_invlaidated
parameter; record niter bound derrived; dump
max_loop_iterations bounds; call try_unroll_loop_completely
even if no niter bound is given.
(canonicalize_induction_variables): Handle irred_invalidated.
(tree_unroll_loops_completely): Handle non-innermost loops;
handle irred_invalidated.
* cfgloop.h (unlop): Declare.
* cfgloopmanip.c (unloop): Export.
* tree.c (build_common_builtin_nodes): Build BULTIN_UNREACHABLE.
* gcc.target/i386/l_fma_float_?.c: Update.
* gcc.target/i386/l_fma_double_?.c: Update.
* gfortran.dg/do_1.f90: XFAIL
* gcc.dg/tree-ssa/cunroll-1.c: New testcase.
* gcc.dg/tree-ssa/cunroll-2.c: New testcase.
* gcc.dg/tree-ssa/cunroll-3.c: New testcase.
* gcc.dg/tree-ssa/cunroll-4.c: New testcase.
* gcc.dg/tree-ssa/cunroll-5.c: New testcase.
* gcc.dg/tree-ssa/ldist-17.c: Block cunroll to make testcase still
valid.
