Hooks can use floating-point values in XFL format, creating them from mantissa and exponent by calling the float_set function. If the mantissa and exponent never change, a more efficient way to do this is to precompute the floating-point value.
This check warns about calls of float_set with constant inputs and proposes to add a tracing statement showing the computed value (so that the user can use it to replace the call). In the special case of 0 mantissa and 0 exponent ("canonical 0"), a replacement value of 0 is proposed directly, with no need to trace it.
