    Add another testcase for PR 110266
    
    Since the combining of sin/cos into cexpi is depedent
    on the target, this adds another testcase which had failed (earlier in
    evpr rather than vrp2) that will fail on all targets rather than
    ones which have sincos or C99 math functions.
    
    Committed as obvious after a quick test.
