S/390: Fix symbol ref alignment

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.

2015-11-23  Robin Dapp  <rdapp@linux.vnet.ibm.com>
