New Release of LIBXSMM

[Hans Pabst]

*LIBXSMM 1.5.1 has been released*, which is mainly a bug-fix release 
gaining its urgency from a fixed Fortran interface (SMM functionality) The 
issue is applicable to CP2K in particular (Fortran), where requesting a JIT 
kernel never returned a suitable PROCEDURE POINTER (always NULL):

>    - New DNN API, sample code, and benchmarks (Googlenetv1, DeepBench, 
>    and Overfeat)
>    - Enabled tiled GEMM support in static/dynamic wrapper; MT support via 
>    libxsmmext
>    - More format variations of sparse matrix multiplication (dense/sparse 
>    etc.)
>    - Sample code showing sparse matrix multiplication (PyFR examples 
>    collection)
>    - Published synchronization layer (atomics, and simple/bare 
>    OS-thread/lock abstraction)
>    - Introduced mini-API for optimized barrier implementation (general 
>    multicore support)
>    - Introduced API for memory allocation (malloc interface); mostly 
>    exposed from internal API
>    - Beside of Intel VTune, now Linux perf and jitdump are supported 
>    (Thank you Maciej D.!)
>    - SPECFEM sample: received nicely written example contribution (Thank 
>    you Daniel P.!)
>    - OSX (incl. "El Capitan") now supports Intel Compiler, Apple/Clang, 
>    and GNU GCC
>    - CRAY's Compiling Environment (CCE) is now supported
>    - PGI compiler is now supported
