[PATCH] D32404: [LV] Make LIT test insensitive to basic block numbering

[Gil Rapaport via Phabricator via llvm-commits]

gilr created this revision.

This patch is part of D28975 <https://reviews.llvm.org/D28975>'s breakdown.

induction.ll encodes the specific (and rather arbitrary) numbers given to predicated basic blocks by the unique naming mechanism, which makes it sensitive to changes in LV's instruction generation order. This patch replaces those specific numbers with a numeric pattern.
