and literals with the 'f32' or 'f64' suffixes work as well. In addition, logging things with the f32 or f64 type works. (float is still assumed to be a synonym for f64).

This commit updates to the latest nightly's syntax where `#[target_feature = "+foo"]` is now deprecated in favor of `#[target_feature(enable = "foo")]`. Additionally `#[target_feature]` can only be applied to `unsafe` functions for now. Along the way this removes a few exampels that were just left around and also disables the `fxsr` modules as that target feature will need to land in upstream rust-lang/rust first as it's currently unknown to the compiler.

Adds a VeriFast solution for challenge 19 (RawVec). Note: this proof does not prove semantic well-typedness of the non-`unsafe` RawVecInner methods listed in the challenge, because they do not satisfy any meaningful kind of semantic well-typedness; see the discussion at rust-lang#283. Resolves rust-lang#283 By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 and MIT licenses. --------- Co-authored-by: Felipe R.

I know you said not to change rustboot, but I spent a bunch of time trying to track down this error given the unfriendly error message from before, so I thought this was worth committing.
I don't know why github included a bunch of other commits in this, but the change to lexer.mll is the only one that matters.
