<title>Fix for codegen Crash in Clang when using locator omp_all_memory with depobj construct (#114221)</title>

<content type='text'>
A codegen crash is occurring when a depend object was initialized with
omp_all_memory in the depobj directive.
https://github.com/llvm/llvm-project/issues/114214(url)
The root cause of issue looks to be the improper handling of the
dependency list when omp_all_memory was specified.

The change introduces the use of OMPTaskDataTy to manage dependencies.
The buildDependences function is called to construct the dependency
list, and the list is iterated over to emit and store the dependencies.

Reduced Test Case : 
```
#include &lt;omp.h&gt;

int main()

{ omp_depend_t obj; #pragma omp depobj(obj) depend(inout: omp_all_memory) }
```

```

This creates an entry with address=nullptr and flag=0x80.
When an 'omp_all_memory' entry is specified any other 'out' or
'inout' entries are not needed and are not passed to the runtime.

<title>[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)</title>

This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.

The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

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.
