81215711a2 Re-enable DAXPY microkernels for x86_64 
as the inaccuracies seen in the original testcase for #1332 appear to be due to an artefact that amplifies the very small rounding differences between FMA and discrete multiply+add

6e70287776 Use generic/dot.c for DSDOT on ARMV5 and above 
The default arm/dot.c is less precise when used for DSDOT, as shown by utest

2359c7c1a9 Use .p2align instead of .align for portability 
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

e7366a4161 Restore the remaining utests (#1462) 
* 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)
