loop-36.c: Reduce amount of iterations to 2 so unrolling still happens.
* gcc.dg/tree-ssa/loop-36.c: Reduce amount of iterations to 2 so unrolling
still happens.
* gcc.dg/ipa/ipacost-1.c: Prevent inlining
* gcc.dg/ipa/ipacost-2.c: Likewise.
* gcc.dg/vect/slp-3.c: Loop is no longer unrolled.
* tree-inline.c (estimate_operator_cost): Add operands;
when division happens by constant, it is cheap.
(estimate_num_insns): Loads and stores are not having cost of 0;
EH magic stuff is cheap; when computing runtime cost of switch,
use log2 base of amount of its cases; builtin_expect has cost of 0;
compute cost for moving return value of call.
(init_inline_once): Initialize time_based flags.
* tree-inline.h (eni_weights_d): Add time_based flag.
