The stdilb code just calls the signed int{32,64} functions,
which gives the right result for the unsigned case anyway.
The various targets didn't consistently define the unsigned
variants in any case.
Properly pick up on ISPC_FORCE_ALIGNED_MEMORY when --opt=force-aligned-memory is used
Fixed usage of loadunpack and packstore to use proper memory offset
Fixed implementation of __masked_load_*() __masked_store_*() incorrectly (un)packing the lanes loaded
Cleaned up usage of _mm512_undefined_*(), it is now mostly confined to constructor
Minor cleanups

__any() and __none() speedups.

This forces all vector loads/stores to be done assuming that the given
pointer is aligned to the vector size, thus allowing the use of sometimes
more-efficient instructions. (If it isn't the case that the memory is
aligned, the program will fail!).
- exported structs now get protected with #ifdef/#define blocks (allows including multiple ispc-generated header fiels into the same c source
- when creating offload stubs, encountering a 'export' function for which we cannot produce a stub will only trigger a warning, not an error.
Cilk (cilk_for), OpenMP (#pragma omp parallel for), TBB(tbb::task_group and tbb::parallel_for)
as well as a new pthreads-based model that fully subscribes the machine (good for KNC).
With major contributions from Ingo Wald and James Brodman.
Introduced knc2x.h which supprts 2x interleaved code generation for KNC (use the target generic-32).
This implementation is even more experimental and incomplete than knc.h but is useful already (mandelbrot works for example)
knc.h:
Switch to new intrinsic names _mm512_set_1to16_epi32() -> _mm512_set1_epi32(), etc...
Fix the declaration of the unspecialized template for __smear_*(), __setzero_*(), __undef_*()
Specifically mark _mm512_undefined_*() a few vectors in __load<>()
Fixed implementations of some implementations of __smear_*(), __setzero_*(), __undef_*() to remove unecessary dependent instructions.
Implemented ISPC reductions by simply calling existing intrinsic reductions, which are slightly more efficient than our precendent implementation. Also added reductions for double types.
