codegen crash in Clang occurring when a depend object was initialized with omp_all_memory locator in the depobj directive.
Here is reduced test case :

#include <omp.h>
int main()
{ omp_depend_t obj;
 #pragma omp depobj(obj) depend(inout: omp_all_memory)
 }

Fix for codegen Crash in Clang when using locator omp_all_memory with…
44a6b3a 
… depobj construct (#114221)

A codegen crash is occurring when a depend object was initialized with
omp_all_memory in the depobj directive.
#114214
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 :
