Sanjoy Das 0015e5a088 [IndVars] Preserve LCSSA in eliminateIdentitySCEV 
Summary:
After r249211, SCEV can see through some LCSSA phis.  Add a
`replacementPreservesLCSSAForm` check before replacing uses of these phi
nodes with a simplified use of the induction variable to avoid breaking
LCSSA.

Fixes 25047.

Depends on D13460.
