[Patch, fortran] PR24524 - Fortran dependency checking should reverse loops

[Tobias Burnus]

Paul,

regarding the dump the following looks wrong:

<bb 9>:
  D.1619_93 = A.11[3];
  D.1620_94 = (*D.1619_93)[1]{lb: 1 sz: 1};
  if (D.1620_94 != D.1558_151)
    goto <bb 12>;
  else
    goto <bb 10>;

A.11[3] is "3" but D.1558_151 is b[3][1], which is 4 - thus this one fails.

As my trunk is still bootstrapping, I cannot apply your patch and test
it properly; I also have not yet looked at the patch itself.

Tobias
