The provided patch contains numerous changes across multiple LLVM IR files, primarily focused on restructuring control flow and improving code generation. Here are the major changes:

1. Control Flow Restructuring: Several functions have been modified to restructure their control flow by introducing new basic blocks (e.g., .preheader blocks) and adjusting phi nodes accordingly. This is evident in files like abcMerge.ll, extraUtilDsd.ll, and giaMini.ll, where loops now use preheaders for better optimization opportunities.

2. Phi Node Adjustments: In many cases, phi nodes have been updated to reflect new control flow paths. For example, in assimp/optimized/BlenderTessellator.ll, phi nodes were adjusted after splitting critical edges or adding new predecessors to basic blocks.

3. Critical Edge Splitting: Critical edges were split in several places to facilitate optimizations. This can be seen in box2d/optimized/geometry.ll and bullet3/optimized/MultiBodyTreeImpl.ll, where additional blocks were introduced to handle transitions between loop iterations and exits cleanly.

4. Loop Optimization Enhancements: Loop-related transformations such as loop unrolling, vectorization, and induction variable simplification were enhanced. Files like arrow/optimized/decimal.ll show improved handling of induction variables and reduced redundant computations within loops.

5. Memory Access Pattern Improvements: Memory access patterns were optimized in some instances by reordering loads/stores or eliminating unnecessary ones. For instance, in darktable/optimized/CrwDecompressor.ll, certain load instructions were moved out of loops or replaced with more efficient alternatives.

These changes collectively aim to improve performance through better utilization of CPU resources, reduced instruction count, and enhanced data locality.
