Kernel-nice.853 patched for Spur by SpurBootstrapMonticelloPackagePatcher * Cog-tpr.154

Introduce an isAnExactFloat test, which is true when a Number can be converted as Float exactly.
Use this to boost some mixed arithmetic comparisons by avoidance of Float>>asTrueFraction in more cases.
Use this to make Fraction>>hash more explicit.
While at it, improve a bit the Fraction>>hash in inexact case (previous naive bitXor: causes too many collisions)
Since some hash has been modified, rehashAll in postscript.
