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

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)

Revert insiduous suppression of the -fopenmp flag in the LAPACK subtree
...
This was added in #1046 citing a problem with mingw, but in effect it quietly reduces thread safety on all non-Windows platforms (while -fopenmp is already disabled for Windows builds through the toplevel Makefile.system). Removing the filter fixes #1425

Fixes #1452 and is more in line with how ATLAS does it. The earlier fix from #356 only moved the bug elsewhere, but we will never want the iterative rescaling to change the dflag setting and variable associations with each cycle.

Even if we're directly using the win32 threading driver and not pthreads,
pthread_atfork still works fine to register a pre-fork handler, and is
