As far as I can tell, this doesn't make rust compile any faster, but it does at least remove one level of indirection on malloc, which might help speed up some operations.
This allows read_option to be used with a custom option type instead of just core::Option.

@nikomatsakis pointed out that `fn read_option<T>(&self, f: &fn() -> T) -> Option<T>` should have this syntax so it can work with custom option types: `fn read_option<T>(&self, f: &fn(bool) -> T) -> T`. Also, this also includes some `#[inline(always)]` on the memory functions in `src/libcore/unstable/lang.rs` to reduce one level of indirection when allocating memory.

Rustup with git subtree The commits from the last rustup rust-lang#5587, are again included in this rustup, since I rebased the rustup. Lesson learned: never rebase, only merge when working with git subtree. changelog: none
