Libabigail's DWARF reader does not support the DW_AT_count attribute
used to specify the number of elements in an array subrange. Rather,
it uses the DW_AT_lower_bound and DW_AT_upper_bound attributes that
are emitted by GCC. Recent versions of Clang, on the other hand, use
the DW_AT_count attribute.
This patch adds support for the DW_AT_count attribute too.

new static function.
(build_array_type): Support the DW_AT_count attribute.

* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-clang-report-0.txt:
New test reference output.
* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-gcc.so:
New test binary input.
* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-gcc2.so:
New test binary input.
* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-gcc-report-0.txt:
New test reference output.
* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long.c: Source
code for the binaries above.
