Sanjoy Das 5c8bead46d [IndVars] Don't break dominance in eliminateIdentitySCEV

Summary:
After r249211, `getSCEV(X) == getSCEV(Y)` does not guarantee that X and
Y are related in the dominator tree, even if X is an operand to Y (I've
included a toy example in comments, and a real example as a test case).

This commit changes `SimplifyIndVar` to require a `DominatorTree`.  I
don't think this is a problem because `ScalarEvolution` requires it
anyway.

Fixes PR25051.

Depends on D13459.

Change the write modes to "binary" so that line endings do not get munged on Windows. Otherwise, when this script is run, all files created on Windows have CRLF instead of LF line endings.
