-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
