Subject: test: cover subranges with present DW_AT_count attribute

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.

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