Decode a float into integers
The `integer_decode()` function decodes a float (f32/f64) into integers containing the mantissa, exponent and sign. It's needed for `rationalize()` implementation of #9838. The code got ported from ABCL [1]. [1] http://abcl.org/trac/browser/trunk/abcl/src/org/armedbear/lisp/FloatFunctions.java?rev=14465#L94
