Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID
...
This is done to avoid odd test failures, like the one fixed in r171243.

Indvars: Don't recursively delete instruction during BB iteration.
...
This can invalidate the iterators leading to use after frees and crashes.

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.

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.
