Fix 61441 [5/5] Disable various transformations for signaling NaN operands

Hi, This patch avoids various transformations with signaling NaN operands when flag_signaling_nans is on, to avoid folding which would lose exceptions. A test case for this change is also added as part of this patch. Regards, Sujoy 2015-11-26 Sujoy Saraswati PR tree-optim

Fix 61441 [4/5] Produce quiet NaN for real value operations

Hi, This patch makes resulting NaN values to be quiet NaN for real value operations, irrespective of the flag_signaling_nans flag. The caller has the responsibility to avoid the operation if flag_signaling_nans is on. Regards, Sujoy 2015-11-26 Sujoy Saraswati PR tree-optimiza

Fix 61441 [3/5] Remove flag_errno_math check for RINT
