Integrate LLVM to llvm/llvm-project@1e0899794dd4 (#24610)

Adapted a LLVMCPU and a LLVMGPU codegen test to not expect the
previously incorrectly emitted "nuw" flag.
This has been fixed in LLVM in this commit:
[mlir][MemRefToLLVM] fix incorrect nuw on GEP/mul when lowering
memref.load/store with negative strides (#204309)
    
Finding the commit that caused the change and understanding the effect
has been assisted by Claude Code.
The changes to the tests have been manually checked. The strides are
dynamic, so negative strides are possible and "nuw" should not be there.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
