be258a2c - [SSAUpdaterBulk] Fix incorrect live-in values for a block. (#131762)

[SSAUpdaterBulk] Fix incorrect live-in values for a block. (#131762) The previous implementation incorrectly calculated incoming values from loop backedges, as demonstrated by the tests. The issue was that it did not distinguish between live-in and live-out values for blocks. This patch addresses the problem and fixes https://github.com/llvm/llvm-project/pull/131761. To avoid bloating storage in `R.Defines`, processing data has been moved to a temporary map `BBInfos`. This change helps manage heap allocation more efficiently and likely improves caching.
