2019-02-01combine: Use TDF_DETAILS for "can't combine" dump printsSegher Boessenkool2-3/+8
Some people use the -fdump-rtl-combine dumps (instead of the -da or -fdump-rtl-combine-all dump), but the "Can't combine iN into iM" messages do not make any sense if the failed combine attempts are not printed otherwise. So let's change that. * combine.c (try_combine): Do not print "Can't combine" messages unless printing failed combination attempts. From-SVN: r268453

In 89089, we were never actually setting DECL_SIZE on an empty data member, because its type is a POD, so we didn't set it in the maybe-overlapping section. Fixed by also handling empty types there. In 88865, we were failing to consider empty data members in include_empty_classes. Fixed by making end_of_class always include them. While looking at these I noticed that the ABI says that a potentially-overlapping data member makes its class non-layout-POD, and that an empty data member doesn't prevent its class from being empty, so I've implemented those points as well.
