[PATCH 8/7] [D] libiberty: Add support for specialized template parameters

[Iain Buclaw]

One last thing that was added in the next D version's ABI (and I
subsequently missed).

This is a trivial patch to just ignore the new mangle symbol.

libiberty/ChangeLog:

2015-05-13 Iain Buclaw  <ibuc...@gdcproject.org>

    * d-demangle.c (dlang_template_args): Skip over specialized template
    parameters in mangled symbol.
    * testsuite/d-demangle-expected: Add coverage and unittest for specialized
    template parameters.
