Anton Blanchard cf2a8e410c Fix SEGV in cdot_power9 
We were corrupting r2 because the local entry wasn't being
setup correctly.

Andreas Arnez d117dfd505 Change bad usage of "asum" to "sum" in ZARCH versions of ?sum 
The ZARCH implementations of ?sum contain a cut & paste-error: An inline
assembly argument is named "sum", but the assembly references "asum"
instead.  The mismatch causes a build error.  This is fixed.

Wang, Long 0caf1434c9 Fix the integer overflow issue for large matrix size 
For large matrix, e.g. M=N=K, and M>1290, int mnk=M*N*K will overflow.
This will lead to wrong branching to single-threading. The performance
is downgraded significantly.

Martin Kroeker b3ac6ee222
Define alternate kernels for big-endian PPC970 
The altivec versions of SGEMM and CGEMM fail most test in LAPACK-TESTING when compiled for big endian, STRSM/CTRSM even cause segfaults. The rot kernels either fail the corresponding utest or lead to failures in LAPACK-TESTING.
