initial josh subtree sync This demonstrates what a josh-based rustup would look like with my patched josh. To create it I did ``` git fetch http://localhost:8000/rust-lang/rust.git:start=75dd959a3a40eb5b4574f8d2e23aa6efbeb33573[:prefix=src/tools/miri]:/src/tools/miri.git master git merge FETCH_HEAD ./rustup-toolchain HEAD && ./miri fmt git commit -am rustup ``` Unlike the [previous attempt](rust-lang/miri#2554), this does not add a new root commit to the repo. Once we merge this, we committed to using josh for subtree syncing, and in particular a version of josh that includes josh-project/josh#961 (or something compatible).

This commit makes benchcomp delete fresh copies of benchmark directories after running the benchmark suite, by default. This is to save disk space, especially on CI machines which do not have enough disk space to run the perf suite. The new behavior can be turned off with the new --no-cleanup-run-dirs flag.

This commit converts
ast::identinto a boxed string with the intent of avoiding copies (at the expense of more refcounting, and another level of indirection through the box). The end goal is to convert idents into interned, boxed strings to avoid expensive string comparisons.This makes the code considerably uglier with lots of boxing and dereferencing. It cuts 2% at most from rustc compile times.
