This patch enables the use of `___kmpc_alloc_shared` to allocate dynamically sized allocation on AMD GPUs. For example:

  #pragma omp target
  {
    int N = 10;
    double A[N];
    ...
  }

This will generate a pair of `__kmpc_alloc_shared / __kmpc_free_shared` to handle the allocation and deallocation of `A` inside the target region.
