Power10 fixes

POWER10: Improve axpy performance

POWER: Added special unrolled vectorized versions of "Solve" for specific si…

This patch aligns the stores to 32 byte boundary for saxpy and daxpy
before entering into vector pair loop. Fox caxpy, changed the store
instructions to stxv to improve performance of unaligned cases.

Revert PR747 - SYRK parameter changes for Haswell and related targets

Add msa support for loongson

1. Using core loongson3r3 and loongson3r4 for loongson
2. Add DYNAMIC_ARCH for loongson

MIPS: Fix two bugs

Fix test errors reported by cblas_cgemm & cblas_ctrmm

The cgemv and zgemv test case will call cgemv_n/t_msa.c zgemv_n/t_msa.c files in MIPS environment.
When the macro CONJ is defined, the calculation result will be wrong due to the wrong definition of OP2.
This patch updates the value of OP2 and passes the corresponding test.

The swap test case will call sswap_msa.c and dswap_msa.c files in MIPS environmnet.
When inc_x or inc_y is equal to zero, the calculation result of the two functions will be wrong.
This patch adds the processing of inc_x or inc_y equal to zero, and the swap test case has passed.

Fix 32 and 64bit builds on SPARC with SolarisStudio compilers

rebase

The file cgemm_kernel_8x4_msa.c holds the MSA optimization
codes of cblas_cgemm and cblas_ctrmm. It defines two
macros: CGEMM_SCALE_1X2 and CGEMM_TRMM_SCALE_1X2. The pc1
array index in the two macros should be 0 and 1.

in DTRSM and STRSM, to improve performance in Power9 and Power10.

Avoid concurrent inclusion of libgomp and libomp in clang+gfortran builds

Improve the performance of zasum and casum with AVX512 intrinsic

Fix 32bit x86 builds and add workaround for x86_64 miscompilations by gcc 4.6 (including our Travis setup)

link math lib on FreeBSD

POWER10: Update param.h

Increasing the values of DGEMM_DEFAULT_P and DGEMM_DEFAULT_Q helps
in improving performance ~10% for DGEMM.
