    arc: Update tumaddsidi4 test.
    
    The test is using -O1 and, the macu instruction is generated by the
    combiner and not in the expand step. My previous "arc: Improve code
    gen for 64bit add/sub operations." is actually splitting the 64-bit
    add in the expand, leading to the impossibility to match the multiply
    and accumulate on 64 bit datum by the combiner, hence, the error. This
    patch is stepping up the optimization level which will generate the
    macu instruction at the expand time.
