Fix issue rust-lang#3645

Copy the keyword list, and add `self` so that it is somewhat highlighted
(being liberal with the correct categories).

This reverts commit f63efdc.

Closes rust-lang#4738.

The `std::smallintmap` module doesn't use an implicit @ box so I just added that explicitly for now to make porting simple.

Patch for rust-lang#4517

This works for fixed vectors, but I am unclear how slices should be printed, simply '&[...]'  or...

e.i. How should regions be printed?

Note on `struct_elt`: the comment is wrong, it actually dereferences the nth element of LLVM struct type if it is a pointer. That's why `T_ptr` is removed in `callee.rs`.

Copy the keyword list from rust.vim, and add `self` so that it is highlighted
(being liberal with the correct categories).

I'm not quite willing to dive in to clean up the emacs code yet, but at least this gets a (more) modern syntax highlighting list.

I also deleted a test that would be entirely useless without capture clauses.
