[LibCallsShrinkWrap] Set IsFPConstrained is true for creating quiet floating comparision if function has strictfp attribute

Browse Source 
Create a quiet floating-point comparision if function has strictfp attribute.
Avoid unexpected FP exception raised during libcall domain error checking.
It raises an FP exception only in case where an input is a signaling NaN.
