The `integer_decode()` function decodes a float (f32/f64) into integers containing the mantissa, exponent and sign. It's needed for `rationalize()` implementation of rust-lang#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

[1] http://abcl.org/trac/browser/trunk/abcl/src/org/armedbear/lisp/FloatFunctions.java?rev=14465#L94 I got the permission to use this code for Rust from Peter Graves (the ABCL copyright holder) . If there's any further IP clearance needed, let me know.
