This patch fixes the treatment of symbol ref alignments for
arrays and structs in S390. Until now, the NOT_NATURALLY_ALIGNED flag
was not correctly set for array elements and structs larger than 8
bytes. Therefore, load relative instructions that require a specific
alignment would not always be generated. This patch uses separate flags
for 2-, 4-, and 8-byte alignment to fix the problem.
gcc/testsuite/ChangeLog:
2015-11-23 Robin Dapp <rdapp@linux.vnet.ibm.com>
* gcc.target/s390/load-relative-check.c: New test to check
generation of load relative instructions.

* config/s390/s390.h: Add new symref flags, _NOTALIGN2 etc.

In LTO we do not compute TYPE_CANONICAL of pointers.

that pointers do not have canonical type that would make us believe
they are different.
* alias.c (get_alias_set): Do structural type equality on pointers;
enable pointer path for LTO; also glob pointer to vector with pointer
to vector element; glob pointers and references for LTO; do more strict
sanity checking about build_pointer_type returning the canonical type
which is also the main variant.
(record_component_aliases): When component type is pointer and we
do LTO; record void_type_node alias set.

This is a backport of https://golang.org/cl/17154.
The gccgo bug report https://gcc.gnu.org/PR65785 points out that the
multicast listen tests will use the network even with -test.short.
Fix test by checking testing.Short with a nil interface.
