Andrew Pinski 9438c98dca openmp: Fix omp for static schedule loop with pointers [PR97898]
When r0-122699-gea3a0fdefa353d was done to fix up handling of
gimple statements in openmp expand, there was one spot which did:
```
if (DECL_P (vback) && TREE_ADDRESSABLE (vback))
  t = force_gimple_operand_gsi (&gsi t, true
```
While other locations did:
```
t = force_gimple_operand_gsi (&gsi t, DECL_P (vback) && TREE_ADDRESSABLE (vback) ...
```

This fixes that one location which fixes up openmp for static scheduling with
a pointer as the induction variable.
Basically with a pointer type, we need to convert the rhs of the POINTER_PLUS
to be the same as size_type and with that conversion, the POINTER_PLUS becomes
an invalid gimple.

I don't think this is a regression but this is a small fix up which has now
shown up twice.

Bootstrapped and tested on x86_64-linux-gnu.

	PR middle-end/97898

gcc/ChangeLog:

	* omp-expand.cc (expand_omp_for_static_chunk): Don't
	conditionalize the call to force_gimple_operand_gsi on DECL_P/TREE_ADDRESSABLE
	but rather pass that as the 3rd argument.

gcc/testsuite/ChangeLog:

	* c-c++-common/gomp/pr97898-1.c: New test.
