[github-actions]

This patch implements several key optimizations across multiple benchmarks, primarily focused on improving control flow and memory access patterns in LLVM IR. The major changes are:

1. Store Hoisting and PHI Node Consolidation: Multiple functions now hoist redundant stores (e.g., store i64 0, store i8 0, store ptr null) out of conditional branches into a single unified store at a merge point, using PHI nodes to select the correct pointer operand. This reduces code duplication and improves cache behavior.

2. Conditional Branch Simplification: Several switch instructions have been restructured to reduce the number of cases or redirect fallthrough targets, often by merging branches or adjusting default labels. This simplifies CFG structure and enables further optimization.

3. Exception Handling Cleanup: In multiple functions (e.g., clap-rs, coreutils-rs, influxdb-rs), landing pads and exception resumes have been refactored: duplicated cleanup blocks are eliminated, PHI nodes for exception operands are consolidated, and stores to local variables (e.g., store ptr null) are moved into common resume paths.

4. TBAA Metadata Updates: Several load and store instructions have updated TBAA metadata tags (e.g., !tbaa !65 → !tbaa !66, !tbaa !66 → !tbaa !67) to reflect more precise type information or layout changes, improving alias analysis accuracy.

5. Dead Code Elimination and Instruction Reordering: Redundant stores (e.g., duplicate store i8 0, store i64 0) and unreachable basic blocks (e.g., .split24.i, .split.i, ._crit_edge.i.i.i) have been removed. Some br instructions were redirected to skip unnecessary intermediate blocks, tightening control flow.

These changes collectively improve IR quality by reducing redundancy, simplifying control flow, enhancing memory safety via precise TBAA, and enabling downstream optimizations like vectorization and register allocation.
