[PATCH v2] Skip constant folding for fmin/max when either argument is sNaN [PR105414]

Hi, This patch skips constant folding for fmin/max when either argument is sNaN. According to C standard, fmin(sNaN, sNaN）= qNaN, fmin(sNaN, NaN) = qNaN So signaling NaN should be tested and skipped for fmin/max in match.pd. The V2 patch splits the for loop and keeps MIN/MAX_EXPR
