Matthew Simpson aceef6fa37 [LV] Merge floating-point and integer induction widening code ...

This patch merges the existing floating-point induction variable widening code
into the integer induction variable widening code, creating a single set of
functions for both kinds of inductions. The primary motivation for doing this
is to enable vector phi node creation for floating-point induction variables.
