Fix output_indirect_string so that it does not output strings that
have already been written to the .debug_str.dwo section.

This is a backport of  part of an unrelated change from upstream 4.7:
http://gcc.gnu.org/ml/gcc-cvs/2011-05/msg00130.html

Tested: bootstrap, core, mantle, crust (in progress).

        * dwarf2out.c (output_indirect_string): Check for DW_FORM_strp
        instead of presence of label and non-zero refcount.
