Make array symbol reading resilient to incomplete DWARF.

Summary:
GCC emits DW_TAG_subrange_type for static member arrays, but with no
attributes. This in turn results in wrong type/value of the array when
printing with 'target variable <array var name>'. This patch fixes this
so that the array value is printed in this format:

    (<element type> []) <array var name> = {}

Earlier, the array was being interpreted to be of its element type.

Note: This does not fix anything to do with 'expr' or 'p' commands.
Those commands still error out complaining about incomplete types.
