Title: restored ISPC_FORCE_ALIGNED_MEMORY 

Fixed knc-i1x16.h to use

#define ISPC_FORCE_ALIGNED_MEMORY
aligned load/stores
#else
unaligned load/store
#endif

However, `__load<64>`/`__store<64>` will still be unaligned, unless ISPC_FORCE_ALIGNED_MEMORY is set, due to fails (see issue #632 & output of `grep knc::fails knc-i1x16.h`).
