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

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.

Alexey Bataev b08f89ffc1 [OPENMP] Fix for http://llvm.org/PR24371: Assert failure compiling blender 2.75.
blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables.
We have to rebuild several expression to be sure that all variables are unique.

Alexey Bataev 9c82103743 [OPENMP] Allow to use global variables as lcv in loop-based directives.
For proper codegen we need to capture variable in the OpenMP region. In loop-based directives loop control variables are private by default and they must be captured in this region. There was a problem with capturing of globals, used as lcv, as they was not marked as private by default.

Alexey Bataev 9aba41c822 [OPENMP] Temporary fix for processing of global variables in loops.
Currently there is a bug in processing of global variables used as loop control variables in 'omp for/simd' constructs: these globals must be captured as private variables, but currently they are nor. This is a temporary bug fix for this problem until the correct solution is prepared. If a global var used as lcv without explicit mark as a private/linear/lastprivate the error message is emitted.

Alexander Musman a5f070aec0 [OPENMP] Loop collapsing and codegen for 'omp simd' directive.
This patch implements collapsing of the loops (in particular, in
presense of clause 'collapse'). It calculates number of iterations N
and expressions nesessary to calculate the nested loops counters
values based on new iteration variable (that goes from 0 to N-1)
in Sema. It also adds Codegen for 'omp simd', which uses
(and tests) this feature.
