Avoid calling AVX code in library static initialization
Despite 26072b8db7ba53f00c83197cb064229a76001989 and
12c6b1ef6a824b09778163ec83fc44bb196e65db, Linux builds using
RH devtoolset-7 gcc7 still hit occasional unit test crashes
with illegal instructions.
Backtrace is always:
> #0 __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535) at core/sc/source/core/tool/arraysumAVX.cxx:20
> #1 _GLOBAL__sub_I_arraysumAVX.cxx(void) () at core/sc/source/core/tool/arraysumAVX.cxx:112
>
So lets make sure initializer is run only on function entry.
