Power8 blas3 copy-pack routines

Replace .align with .p2aligns in dscal.c and the Nehalem microkernels as well

Fix limited DSDOT precision on arm,aarch64 and zarch

The default arm/dot.c is less precise when used for DSDOT, as shown by utest

The implementation in arm/dot.c has lower precision, as shown by the utest for dsdot.

The OSX assembler apparently mishandles the argument to decimal .align, leading to a significant loss of performance 
as observed in #730, #901 and most recently #1470

* Restore the remaining utests

* Try fork test on Cygwin and Linux only, it hangs on at least ARMv8/Android as well

* Use generic sswap/dswap kernels for NEHALEM 32bit to fix fault found by the restored swap utest

* Disable zdotu test for MS cl to work around runtime error -1073741819 on AppVeyor for now
(probably coding error in the initialization of the complex numbers or wrong choice of zdotu API)

small corrections

Initialize unitialized values for repeated calls

small fix inside ifdef z13mvc . (z13mvc code is not used in production)

Fixes #1432 (and possibly other DTRMM-related failures on Haswell and related architectures when built with cmake)

(Z13 ) Blas1 mikrokernels can be inlined by gcc. Refactoring,fixes,tunings

(Z systems Z13) small fixes, some (i(dz)amin,i(dz)amax,(dz)dot,(dz)asum) mikrokernels…

Address warnings #1357

Tag %1 and %2 as both input and output operands

fix from #1292 extended to the other gemv microkernels

Tag %1 and %2 as both input and output

Address few more warnings

The inline assembly modifies its input operands, so mark them as output to avoid surprises with optimization. Fixes #1292

related to issue #1332

The testcase from #1332 exposes a problem in daxpy_microk_haswell-2.c that is not seen with
any of the other Intel x86_64 microkernels.

* dead increments in driver/level2

* dead increments in kernel/generic

* part dead increments in kernel/x86_64

Add trivially optimized DSDOT for POWER8
