Fixes PR9730: indvars: An asserting value handle still pointed to this value

Modified LinearFunctionTestReplace to push the condition on the dead
list instead of eagerly deleting it. This can cause unnecessary
IV rewrites, which should have no effect on codegen and will not be an
issue once we stop generating canonical IVs.

If converter was being too cute. It look for root BBs (which don't have

that doesn't work when the CFG has infinite loops. Simply do a linear
