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.

The align value in DIGlobalVariable description specifies variable alignment in
|
||||
case it was forced by C11 _Alignas(), C++11 alignas() keywords or compiler
|
||||
attribute __attribute__((aligned ())). In other case (when this field is missing)
|
||||
alignment is considered default. This is used when producing DWARF output
|
||||
for DW_AT_alignment value.
