…#951) as title. There are two highlights of the PR 1. The PR introduced a new test file to cover neon intrinsics that move data, which is a big category. This would the 5th neon test file. And we're committed to keep total number of neon test files within 6. This file uses another opt option instcombine, which makes test LLVM code more concise, and our -fclangir generated LLVM code would be identical to OG with this. It looks like OG did some instcombine optimization. 2. `getIntFromMLIRValue` helper function could be substituted by [`mlir::cir::IntAttr getConstOpIntAttr` in CIRGenAtomic.cpp](https://github.com/llvm/clangir/blob/24b24557c98d1c031572a567b658cfb6254f8a89/clang/lib/CIR/CodeGen/CIRGenAtomic.cpp#L337). The function `mlir::cir::IntAttr getConstOpIntAttr` is doing more than `getIntFromMLIRValue`, and there is FIXME in the comment, so not sure if we should just use `mlir::cir::IntAttr getConstOpIntAttr`, either is fine with me.
