Implemented codegen for the iterator expression in the depend clauses.
Iterator construct is emitted the following way:
iterator(cnt1, cnt2, ...), in : <dep>
<TotalNumDeps> = <cnt1_size> * <cnt2_size> * ...;
kmp_depend_t deps[<TotalNumDeps>];
deps_counter = 0;
for (cnt1) {
for (cnt2) {
...
deps[deps_counter].base_addr = &<dep>;
deps[deps_counter].size = sizeof(<dep>);
deps[deps_counter].flags = in;
deps_counter += 1;
...
}
}
For depobj construct the codegen is very similar, but the memory is
allocated dynamically and added extra first item reserved for internal use.
clauses.
Implemented codegen for array shaping operation in depend clauses. The
begin of the expression is the pointer itself, while the size of the
dependence data is the mukltiplacation of all dimensions in the array
shaping expression.
variables.
Loop control variables are private in loop-based constructs and we shall
take this into account when generate the code for inner constructs.
Currently, those variables are reported as shared in many cases. Moved
the analysis of the data-sharing attributes of the loop control variable
to an early semantic stage to correctly handle their attributes.

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

in C.
If we try to get the lvalue for thread_id variables in inlined regions,
we did not use the correct version of function. Fixed this bug by adding
overrided version of the function getThreadIDVariableLValue for inlined
regions.
