[VPlan] Use target's index type for {First,Last}ActiveLane instead of i64 (#186361) 
Fixes #186005

On RV32 with zve32x, i.e. no legal 64 bit types either scalar or vector,
@llvm.cttz.elts.i64 cannot be lowered and so returns an illegal cost for
scalable VFs. However VPInstruction::FirstActiveLane and
VPInstruction::LastActiveLane always use a hardcoded i64 type.

This causes a legacy/VPlan cost model mismatch in the live-out.ll test,
and in early-exit-live-out.ll prevents the scalable VF from being
chosen.

This PR teaches the two VPInstructions to use the target's index type,
i.e. the width of a pointer in the default address space, so it will
generate a 32 bit cttz.elts on RV32. This should be large enough to hold
the maximum number of elements in a vector, as if the vector was any
bigger it would imply it isn't accessible by memory.

I considered using the canonical IV type but I don't think that will
work since the canonical IV can be i64 on RV32, and it causes
regressions due to extra zexting on 64-bit targets with a 32-bit IV.
