Use the Rust implementation of udivsi3 on ARM
...
Although compiler-rt presumably has a more optimized implementation written in
assembly, it appears buggy for whatever reason, causing #173 .
For now let's see if integration into rust-lang/rust will work with the
Rust-defined implementation!

* Disable `compiler_builtins` attribute on `feature = "gen-tests"`
* Disable mangling on `feature = "gen-tests"` instead of `cfg(test)`

Objects in compiler-rt may have two symbols, so this makes sure that we don't
bring in those objects by accident by defining the aliases ourselves.

Use traits instead of macros for shift intrinsics
...
This is an attempt to tidy up the definition of intrinsics by making them more
rust-like at the definition site and using traits instead of macros for the
definition. Additionally the helper macro, `intrinsics!`, now fills in a
definition for #[cfg]'d off intrinsics when compiling with C code
