[boost] cstdint.hpp patch for Cray X1

From: Dan Gohman (djg_at_[hidden])

The recent change to boost/cstdint.hpp for Cray systems is not
appropriate for the Cray X1. It has a 16-bit short type, however there
are performance penalties associated with it.

The following patch for cstdint.hpp sets up the appropriate typedefs for
this platform.
