Description

[LFTR] Rename variable to minimize confusion [NFC]

(Recommit of r363293 which was reverted when a dependent patch was.)

As pointed out by Nikita in D62625, BackedgeTakenCount is generally used to refer to the backedge taken count of the loop. A conditional backedge taken count - one which only applies if a particular exit is taken - is called a ExitCount in SCEV code, so be consistent here.
