This will hopefully bring us closer to rust-lang#11937. We're still using gcc's idea of "startup files", but this should prevent us from leaking in dependencies that we don't quite want (libgcc for example once compiler-rt is what we use).

It looks like this is failing on osx due to a missing symbol. Some googling leads me to believe that this symbol comes from libgcc or compiler-rt. Right now we don't know which compiler we're linking with (gcc or clang), so I don't think that this is possible until we bundle |

…ogiq Lint nested binary operations and handle field projections in `eager_transmute` This PR makes the lint a bit stronger. Previously it would only lint `(x < 4).then_some(transmute(x))` (that is, a single binary op in the condition). With this change, it understands: - multiple, nested binary ops: `(x < 4 && x > 1).then_some(...)` - local references with projections: `(x.field < 4 && x.field > 1).then_some(transmute(x.field))` changelog: [`eager_transmute`]: lint nested binary operations and look through field/array accesses r? llogiq (since you reviewed my initial PR rust-lang#11981, I figured you have the most context here, sorry if you are too busy with other PRs, feel free to reassign to someone else then)
