Handle DW_AT_ranges when reading partial symtabs

add_partial_subprogram does not handle DW_AT_ranges, while the full
symtab reader does.  This can lead to discrepancies where a function
is not put into a partial symtab, and so is not available to "break"
and the like -- but is available if the full symtab has somehow been
read.

This patch fixes the bug by arranging to read DW_AT_ranges when
reading partial DIEs.

This is PR symtab/23331.

The new test case is derived from dw2-ranges-func.exp, which is why I
kept the copyright dates.
