should have no performance impact on reasonably modern cpus and fixes occasional crashes in actual user code.

Using "make TARGET=GENERIC" on loongson platform will get the following
error messages:
"make[1]: *** No rule to make target 'sgemm_incopy.o', needed by 'libs'"
Add kernel/mips64/KERNEL.generic to slove the problem.

* Add an ARMV7 iOS build on Travis

* thread_local appears to be unavailable on ARMV7 iOS

* Add no-thumb option for ARMV7 IOS build to get it to accept DMB ISH

* Make local labels in macros of nrm2_vfpv3.S compatible with the xcode assembler

Fix zero initialization for beta=0 case

use immediate initialization instead of multiplication in case register content is a NaN

Fix avx512 sgemm performance bug when ldc is a multiple of 1024

Temporary fix for SKX STRSM

AVX2 STRSM kernels

Setting DYNAMIC_ARCH=1 on POWER9 does not build POWER9 files due to some
compiler version checks.  This patch fixes some of the macros that are used
to check compiler version.  On fixing those checks, there are some new make
failures related to icamin, icamax, isamin, isamax and caxpy files on POWER9.
This patch fixes those failures as well.

Adjust SkylakeX GEMM3M parameters, add an AVX512 STRMM kernel and fix performance bugs in AVX2 s/c/z GEMM

The implementation is a hybird of the ARMV8 one with some of the
improved TX2 rountines along with specifying -march=v8.2-a

[WIP] Add support for Ampere EMAG8180 ARMV8 cpu

the fallbacks from Makefile.L1 assume a combined source for absolute value and non-absolute (with ifdef USE_ABS) but here we have separate implementations

to fix utest failure in new ismin test -  Makefile.L1 defaults look wrong

The was a typo in iamax_sse.S where one of the comparison
was cmpeqps instead of cmpeqss. That misdetected index
for sequences where the minimum value was 0.
