Intercept __spirv_Subgroup2DBlockLoadINTEL and __spirv_Subgroup2DBlockStoreINTEL to detect out-of-bounds accesses from Intel Xe 2D block I/O operations used by CuTe/CUTLASS GEMM kernels. The ASAN pass inserts a check call before each 2D block operation, validating both the register buffer (dst/src pointer) and the surface memory (row-by-row, accounting for pitch stride). The check runs only on the subgroup leader since 2D block I/O is a collective operation.
