[Bug target/32392] Support using -mrecip w/o additional Newton-Raphson run

Confirmed.  For 2 NR steps to reach double precision (we'd miss it by some more
ulps than the 2.5 for float precision) we would need to do at least the second
NR in double precision.  Note that this would make sense only for double
precision input values that are exactly representable in float precision
(otherwise, why the extra precision?).  So practically not worth it.
