Dan Gohman cd83870faf Fix SCEVExpander::visitAddRecExpr so that it remembers the induction variable 
it inserted rather than using LoopInfo::getCanonicalInductionVariable to
rediscover it, since that doesn't work on non-canonical loops. This fixes
infinite recurrsion on such loops; PR7562.

Chris Lattner c558b49f14 first half of a pass through IndVarSimplify::HandleFloatingPointIV, 
this cleans up a bunch of code and also fixes several crashes and
miscompiles.  More to come unfortunately, this optimization
is quite broken.
