C11 alignas instead of unions -- extended alignments This replaces some uses of pg_attribute_aligned() with the standard alignas() for cases where extended alignment (larger than max_align_t) is required.
This patch stipulates that all supported compilers must support alignments up to PG_IO_ALIGN_SIZE, but that seems pretty likely. We can then also desupport the case where direct I/O is disabled because pg_attribute_aligned is not supported.
