This changes the Rust type printers to handle TYPE_CODE_PTR. The
current approach is not ideal, because currently the code can't
distinguish between mut and const, or between pointers and references.
(These are debuginfo deficiencies, for which there are rustc bugs on
file.)
Meanwhile, this at least clears up the case seen in PR rust/23625.
Tested on x86-64 Fedora 28. The nightly compiler gives the best
results, but I regression-tested with stable and beta as well.
