hsmahesha f7de6962c8 [CFE][Codegen][In-progress] Remove CodeGenFunction::InitTempAlloca()
Sequel patch to https://reviews.llvm.org/D111293.

Remove call to CodeGenFunction::InitTempAlloca() from OpenMP related
codegen part.

Also remove the metadata `!llvm.access.group` from the updated lit
tests.

Alexey Bataev bfc8f9e9b0 [clang] Fix computation of number of dependencies using OpenMP iterator,
by Raul Penacoba.

The size of kmp_depend_info and the number of dependencies are computed multiplying the iterator sizes, which not right.
Now size is computed as:

itersize1*numclausedeps1 + itersize2*numclausedeps2 + ... + itersizeN*numclausedepsN

where itersizeX is the size of the iterator and numclausedepsX the number of dependencies in that depend clause.

AndreyChurbanov 9ce2e5e700 Revert "[OpenMP] libomp: implement OpenMP 5.1 inoutset task dependence type"
This reverts commit a1f550e052.

Revert in order to fix backwards compatibility breakage
caused by type size change for task dependence flag.

AndreyChurbanov a1f550e052 [OpenMP] libomp: implement OpenMP 5.1 inoutset task dependence type
Refactored code of dependence processing and added new inoutset dependence type.
Compiler can set dependence flag to 0x8 when call __kmpc_omp_task_with_deps.
Size of type of the dependence flag changed from 1 to 4 bytes in clang.
All dependence flags library gets so far and corresponding dependence types:
1 - IN, 2 - OUT, 3 - INOUT, 4 - MUTEXINOUTSET, 8 - INOUTSET.

Alexey Bataev be99c61588 [OPENMP50]Codegen for iterator construct.
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.

Alexey Bataev e094dd5adc [OPENMP50]Fix size calculation for array shaping expression in the
codegen.

Alexey Bataev a4f74f377b [OPENMP50]Do not imply lvalue as base expression in array shaping
expression.

We should not assume that the base expression in the array shaping
operation is an lvalue of some form, it may be an rvalue.

Alexey Bataev 7842e7ebbf [OPENMP50]Add codegen support for array shaping expression in depend
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.

Alexey Bataev 05be1da24c [OPENMP]Provide correct data sharing attributes for loop control
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.

Alexey Bataev 311a928359 [OPENMP] Fix PR34925: Fix getting thread_id lvalue for inlined regions
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.
