Use 12 as the magic number for our abbreviation data and our

die values. A lot of DIEs have 10 attributes in C++ code (example
clang), none had more than 12. Seems like a good default.

Debug Info: use DW_FORM_ref_addr instead of DW_FORM_ref4 if the referenced DIE
...
belongs to a different compile unit.
DW_FORM_ref_addr should be used for cross compile-unit reference.
When compiling a large application, we got a dwarfdump verification error where
abstract_origin points to nowhere.
This error can't be reproduced on any testing case in MultiSource.
We may have other cases where we use DW_FORM_ref4 unconditionally.
