[09/12] test: cover subranges with present DW_AT_count attribute
Commit Message
From: Sanimir Agovic <sanimir.agovic@intel.com>
The dwarf attribute DW_AT_count specifies the elements of a subrange.
This test covers subranges with present count but absent upper bound
attribute, both with static and dynamic attribute values.

* gdb.dwarf2/count.exp: New file.
