Arm Target Code Generation With Conditional Execution And Neon Simd

Project moved to: https://github.com/llvm/llvm-project

Unique: Leverages ARM conditional execution to eliminate branches in tight loops, reducing branch misprediction penalties and improving code density. Implements sophisticated NEON vectorization that exploits ARM's unique instruction patterns (e.g., lane-wise operations, permutation instructions) that differ from x86 SIMD.

vs others: Generates more compact ARM code than generic code generators by using conditional execution to eliminate branches. Better NEON support than competing compilers because it understands ARM-specific SIMD patterns and lane operations.
