Improve compatibility to CRuby for Float#to_s
...
Bfore:
Float::INFINITY.to_s #=> "inf"
50.0.to_s #=> "50"
1e20.to_s #=> "1e+20"
After / CRuby:
Float::INFINITY.to_s #=> "Infinity"
50.0.to_s #=> "50.0"
1e20.to_s #=> "1.0e+20"

Recover #to_int; ref #4177
...
We have removed implicit conversion to strings using `to_int`. But some
users still using `to_int` as a typical integer method, i.e. they do
string check by code like: `obj.respond_to?(:to_int)`. So we have
recovered the method.

Remove implicit conversion using to_int method.
...
The ISO standard does not include implicit type conversion using
`to_int`. This implicit conversion often causes vulnerability.
There will be no more attacks like #4120 .
In addition, we have added internal convenience method `__to_int` which
does type check and conversion (from floats).
