Installs the miri driver and cargo-miri. <flags> are passed to `cargo
install`. Sets up the rpath such that the installed binary should work in any

+working directory. However, the rustup toolchain when invoking `cargo miri`
+needs to be the same one used for `./miri install`.
./miri build <flags>:
Just build miri. <flags> are passed to `cargo build`.
Build miri, set up a sysroot and then run the driver with the given <flags>.
(Also respects MIRIFLAGS environment variable.)
-The commands above also exist in a "-debug" variant (e.g. "./miri run-debug

./miri fmt <flags>:
Format all sources and tests. <flags> are passed to `rustfmt`.
./miri clippy <flags>:
-Format all sources and tests. <flags> are passed to `cargo clippy`.

./miri many-seeds <command>:
Runs <command> over and over again with different seeds for Miri. The MIRIFLAGS
