Summary:
Added basic representation and parsing/sema handling of array-shaping
operations. Array shaping expression is an expression of form ([s0]..[sn])base,
where s0, ..., sn must be a positive integer, base - a pointer. This
expression is a kind of cast operation that converts pointer expression
into an array-like kind of expression.

The OpenMP specification disallows having zero-length array
sections in the depend clause (OpenMP 5.0 2.17.11).

Summary: this commit adds support to a new dependence type introduced in OpenMP
5.0. The LLVM OpenMP RTL already supports this feature, so we only need to
modify CLANG to take advantage of them.

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

OpenMP 4.5 removed the restriction that array section lower bound must be non negative.
This change is to allow negative values for array section based on pointers.
For array section based on array type there is still a restriction: "The array section must be a subset of the original array."

OpenMP 4.5 adds 'depend(source)' clause for 'ordered' directive to support cross-iteration dependence. Patch adds parsing and semantic analysis for this construct.

Adds parsing/sema analysis/serialization/deserialization for array sections in OpenMP constructs (introduced in OpenMP 4.0).
Currently it is allowed to use array sections only in OpenMP clauses that accepts list of expressions.
