libctf needs to handle DW_AT_count based array sizing
There are two different ways to emit array sizes in dwarf. Clang opts to use the DW_AT_count field to indicate the number of entries that are in the array as opposed to gcc which uses an upper bound attribute. We should support this so we can properly convert and process clang arrays.

This was tested by using the ctf test suite and verifying that it was clean for gcc 4.4.4, 7, and 8. In addition with the test suite improvements that exist for clang, clang8, clang9, and clang10 are all in similar shape with everything passing excepting existing bugs in clang's dwarf generation. I also diffed all the CTF across this change that was generated in the build and it didn't change excepting a small bit in libctf.
