r? @graydon - This is for greater uniformity (for example, macros that generate

way to construct a 1-tuple term.
@graydon , as far as your comment on #4898 - it did turn out to be solvable inside the macro (since @luqmana already fixed it using structs instead), but I still think it's a good idea to allow 1-tuples, for uniformity. I don't think anyone is likely to trip over it, and I'm not too worried that it changes the amount of ambiguity.
This implements a rust tool similar to go's go tool. It acts as a central hub for the tools rustc, rustdoc, rustpkg, rusti, and also provides shortcuts for directly compiling and running a source file either as a normal or a test executable. Default usage message:
```
The rust tool is a convenience for managing rust source code.
It acts as a shortcut for programs of the rust tool chain.
Usage: rust <command> [arguments]
The commands are:
build compile rust source files
run build a executable, and run it
test build a test executable, and run it
doc generate documentation from doc comments
pkg download, build, install rust packages
sketch run a rust interpreter
help show detailed usage of a command
Use "rust help <command>" for more information about a command.
```
These commits take the old bitv implementation and modernize it with an explicit self, some minor touchups, and using what I think is some more recent patterns (like `::new` instead of `Type()`).
Additionally, this adds an implementation of `container::Set` on top of a bit vector to have as a set of `uint`s. I initially tried to parameterize the type for the set to be `T: NumCast` but I was hitting build problems in stage0 which I think means that it's not in a snapshot yet, so it's just hardcoded as a set of `uint`s now. In the future perhaps it could be parameterized. I'm not sure if it would really add anything, though, so maybe it's nicer to be hardcoded anyway.
I also added some extra methods to do normal bit vector operations on the set in-place, but these aren't a part of the `Set` trait right now. I haven't benchmarked any of these operations just yet, but I imagine that there's quite a lot of room for optimization here and there.
Removes the last use of structural records in the pipes extension and with that, libcore has no more structural records.
Also, explicit-self-ification.
This is for greater uniformity (for example, macros that generate
tuples). rustc already supported 1-tuple patterns, but there was no
way to construct a 1-tuple term.
As far as I can tell, the only reason run-pass/type-use-i1-versus-i8
is trying to do a read is because that code was left over from the
original program the issue was found in. When that test is run as
part of check-fast, and apparently only in that case, the test blocks
indefinitely, which is bad.
Consts of such enums are aligned correctly, so we could either misalign
them to match the type_of, or fix the type_of. The latter seems like a
better idea.
* use a proper exported data type with private fields
* implement core::container::Container
* use the current constructor convention
* use explicit self
* get rid of DVec and the mutable fields

`simplify_type` was bogus, as there was no way for it to handle enums
properly. It was also slow, because it created many Rust types at runtime. In
general creating Rust types during trans is a source of slowness, and I'd like
to avoid doing it as much as possible. (It is probably not possible to
eliminate it entirely, due to `subst`, but we should get rid of as much of it
as we can.) So this patch replaces `simplify_type` with `sizing_type_of`,
which creates a size-equivalent LLVM type directly without going through a
Rust type first.
Because this is causing an ICE in Servo, I'm rubber stamping it.
