Rust BPF: Add support for float and signed division

[jackcmay]

Problem

The BPF instruction set does not contain a signed-division instruction and Rust's use of floats includes code that attempts to generate one. Either the Rust code needs to be rewritten, the LLVM back-end needs to compensate and lower those operations to something compatible, or BPF must add a new instruction to support it. Currently, floats are mostly disabled in the core libraries.
