Alexey Bataev bef93a98cd [OPENMP50]Treat range-based for as canonical loop.
According to OpenMP 5.0, range-based for is also considered as a
canonical form of loops.

Alexey Bataev 1be634044d [OPENMP] Update the diagnosis message for canonical loop form, by Chi
Chun Chen.

The previous patch (https://reviews.llvm.org/D54441) support the
relational-op != very well for openmp canonical loop form, however,
it didn't update the diagnosis message. So this patch is simply
update the diagnosis message by adding !=, update the test
related to it, and update the section number for canonical loop
form for OpenMP 5.0 in comment.

Kelvin Li efbe4afbda [OPENMP] Support relational-op != (not-equal) as one of the canonical
forms of random access iterator
    
In OpenMP 4.5, only 4 relational operators are supported: <, <=, >, 
and >=.  This work is to enable support for relational operator 
!= (not-equal) as one of the canonical forms.

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.

Alexey Bataev 5372fb8cc1 [OPENMP] Fix for PR34398: assert with random access iterator if the
step>1.

If the loop is a loot with random access iterators and the iteration
construct is represented it += n, then the compiler crashed because of
reusing of the same MaterializedTemporaryExpr around N. Patch fixes it
by using the expression as written, without any special kind of
wrappings.

Alexey Bataev 5a3af13d93 [OPENMP] Remove extra code transformation.
For better support of some specific GNU extensions some extra
transformation of AST nodes were introduced. These transformations are
very hard to handle. The code is improved in handling of these
extensions by using captured expressions construct.
