We already have several places in this code which reason about whether the inactive lanes are defined, and are about to add one more in D151653 <https://reviews.llvm.org/D151653>. Let's go ahead and common the code so that we don't have the same concept repeating in multiply places.
Asking for review mostly because of the change to computeInfoForInstr. I want a second pair of eyes confirming I'm not missing something there. (All of the removed asserts are covered by the verifier; I checked.)
