[NFC][VPlan] Trim extra spaces in VPDerivedIVRecipe::print during debugging

[sunshaoce]

before:

    EMIT vp<%3> = CANONICAL-INDUCTION ir<0>, vp<%8>
    vp<%4>    = DERIVED-IV ir<%n> + vp<%3> * ir<-1>
    vp<%5> = SCALAR-STEPS vp<%4>, ir<-1>

after:

    EMIT vp<%3> = CANONICAL-INDUCTION ir<0>, vp<%8>
    vp<%4> = DERIVED-IV ir<%n> + vp<%3> * ir<-1>
    vp<%5> = SCALAR-STEPS vp<%4>, ir<-1>
