fixed CMakeLists.txt to avoid warning
rename alignAccess -> applyPadding,deleted  1 call

 - the action is more about padding than the pure alignment (the memory
   area actually gets bigger)
 - if done only before the XMallocSIMD::collect, it uses more memory,
   but all accesses are always aligned
 - if done only after the XMallocSIMD::collect, it might use less
   memory (especially for very small requests), but some accesses might
   not be perfectly aligned
 - if done twice, the second call will be useless
 - now it is done only BEFORE the XMallocSIMD::collect
