Wrap all generated oneMKL C wrappers in try/catch blocks to propagate errors as return codes instead of crashing. LAPACK functions catch computation_error and return info(), while BLAS/sparse functions catch sycl::exception and return -1. Also add syclQueueWait to the SYCL interop layer.
Work around a Blelloch parallel prefix sum correctness issue on Intel GPUs at block sizes >= 128 by defaulting to a block size of 64.
Widen Int8/Int16/Float16 values to Int32 before writing to local memory to avoid clobbering adjacent bytes. Adjusts the local memory size calculation accordingly.
