Alexey Bataev 1c92448656 [OPENMP]Fix PR45439: `omp for collapse(2) ordered(2)` generates invalid
IR.

Fixed a crash because of the not quite correct casting of the value of
iterations.

Alexey Bataev 71ffac21f7 [OPENMP]Fix PR45132: OpenMP doacross loop nest with a decreasing
induction variable abends.

Used incorrect loop bound when trying to calculate the index in the vec
array for doacross construct in the loops with the reverse order.

Alexey Bataev f6a53d63a1 [OPENMP] Set scheduling for doacross loops as schedule, 1.
The default scheduling for doacross loops is changed from static to
static, 1.

Alexey Bataev 0d8fcdf11a [OPENMP]Fix crash for the ordered(n) clause.
If the doacross lop construct is used and the loop counter is declare
outside of the loop, the compiler might crash trying to get the address
of the loop counter. Patch fixes this problem.

Alexey Bataev f138fda5ed [OPENMP] Fix emission of the loop doacross constructs.
The number of loops associated with the OpenMP loop constructs should
not be considered as the number loops to collapse.

Daniel Neilson 6e938effaa Change memcpy/memove/memset to have dest and source alignment attributes (Step 1).
Summary:
  Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset
intrinsics. This change updates the Clang tests for this change.

  The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument
which is required to be a constant integer. It represents the alignment of the
dest (and source), and so must be the minimum of the actual alignment of the
two.

 This change removes the alignment argument in favour of placing the alignment
attribute on the source and destination pointers of the memory intrinsic call.

 For example, code which used to read:
   call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false)
will now read
   call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false)

 At this time the source and destination alignments must be the same (Step 1).
Step 2 of the change, to be landed shortly, will relax that contraint and allow
the source and destination to have different alignments.

Alexey Bataev a8a9153a37 [OPENMP] Support for -fopenmp-simd option with compilation of simd loops
only.

Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.
