[patch, fortran] Check bounds for matrix-vector multiplication

[Thomas Koenig]

Hi Steve,

> Why the duplicate code?  Seems like an OR is needed.

You are quite right.

Here's an updated patch:

        /* Only need to check a single dimension for the A2B2 case for
-        bounds checking, the rest will be allocated.  */
+        bounds checking, the rest will be allocated.  Also check this
+        for A2B1.   */

-      if (gfc_option.rtcheck & GFC_RTCHECK_BOUNDS && m_case == A2B2)
+      if ((gfc_option.rtcheck & GFC_RTCHECK_BOUNDS) && (m_case == A2B2 
|| m_case == A2B1))
         {
           gfc_code *test;
           gfc_expr *a2, *b1;

OK for trunk?
