Fix build failure with GCC 4.8
A user pointed out that the build failed with GCC 4.8. The problem was that the form used by the std::hash specialization of ptid_t was not accepted. This patch rewrites this code into a form that is acceptable to the older compiler. Approved-By: Simon Marchi <simon.marchi@efficios.com>
