  Hi,

When running gdb.dwarf2/dw2-restrict.exp with board cc-with-dwz, we run into:
...
dwz: dw2-restrict: DW_AT_stmt_list not DW_FORM_sec_offset or DW_FORM_data4
...

The problem is that the DW_AT_stmt_list is encoded using DW_FORM_addr, while
DW_FORM_sec_offset or DW_FORM_data4 would be appropriate.  The test-case uses
a dw2-restrict.S which was generated using clang 2.9, which contained a bug
( https://bugs.llvm.org/show_bug.cgi?id=9995 ) causing this problem.

Fix this by regenerating using clang 5.0.1.

Tested on x86_64-linux.

OK for trunk?

Thanks,
- Tom
