Branch: eq-sigill

Changes: niko's operator dispatch + DSTification of PartialEq et al.

make passes, but make check yields 17 run-pass test failures (See the "failures" file attached below). Most failures have empty stdout/stderr. Upon running the compiled tests under gdb, I found that the programs SIGILL (See "backtrace" file attached below). However, when recompiled, the tests run successfully:

$ LD_LIBRARY_PATH=~/tmp/rust/build/x86_64-unknown-linux-gnu/stage2/lib ~/tmp/rust/build/x86_64-unknown-linux-gnu/stage2/bin/rustc concat.rs && ./concat && echo OK
