Johannes Doerfert 6ff380f439 [OpenMP][NFC] Remove SIMD check lines for non-simd tests 
If a test does not contain an " simd" but -fopenmp-simd RUN lines we can
just check that we do not create __kmpc|__tgt calls.

Giorgis Georgakoudis 207b08a913 [OpenMP][NFC] Refactor Clang OpenMP tests using update_cc_test_checks 
This patch refactors a subset of Clang OpenMP tests, generating checklines using the update_cc_test_checks script. This refactoring facilitates updating the Clang OpenMP code generation codebase by automating test generation.

Alexey Bataev 1b93ebccaa [OPENMP]Do not capture base pointer by reference if it is used as a base for array-like reduction. 
If the declaration is used in the reduction clause, it is captured by
reference by default. But if the declaration is a pointer and it is a
base for array-like reduction, this declaration can be captured by
value, since the pointee is reduced but not the original declaration.

Alexey Bataev 8c2f4e0e85 [OPENMP50]Codegen for reduction clauses with 'task' modifier. 
Summary:
Added codegen for reduction clause with task modifier.
```
  #pragma omp ... reduction(task, +: a)
  {
  #pragma omp ... in_reduction(+: a)
  }
```
is translated into something like this:
```
  #pragma omp ... reduction(+:a)
  {
    struct red_input_t {
      void *reduce_shar;
      void *reduce_orig;
      size_t reduce_size;
      void *reduce_init;
      void *reduce_fini;
      void *reduce_comb;
      unsigned flags;
    } r_var;
    r_var.reduce_shar = &a;
    r_var.reduce_orig = &original a;
    r_var.reduce_size = sizeof(a);
    r_var.reduce_init = [](void* l,void*){return *(int*)l=0;};
    r_var.reduce_fini = nullptr;
    r_var.reduce_comb = [](void* l,void* r){return *(int*)l += *(int)r;};
    void *tg = __kmpc_taskred_modifier_init(<loc_addr>,<gtid>,
      <flag - 0 for parallel, 1 for worksharing>,
      <1 - number of reduction elements>,
      &r_var);
    {
    #pragma omp ... in_reduction(+: a) firstprivate(tg)
    ...
    }
    __kmpc_task_reduction_modifier_fini(<loc_addr>,<gtid>,
      <flag - 0 for parallel, 1 for worksharing>);
  }
```
