DebugInfo: support for DWARFv5 DW_AT_alignment attribute
* Assume that clang passes non-zero alignment value to DIBuilder
only in case when it was forced by C++11 'alignas', C11 '_Alignas'
or compiler attribute '__attribute__((aligned (N)))'.
* Emit DW_AT_alignment if alignment is specified for type/object.
