C11 alignas instead of unions This changes a few union members that only existed to ensure alignments and replaces them with the C11 alignas specifier.
This change only uses fundamental alignments (meaning approximately alignments of basic types), which all C11 compilers must support. There are opportunities for similar changes using extended alignments, for example in PGIOAlignedBlock, but these are not necessarily supported by all compilers, so they are kept as a separate change.
