dd64bd83b7 std: Move NativeMutex from &mut self to &self
The proper usage of shared types is now sharing through `&self` rather than
`&mut self` because the mutable version will provide stronger guarantees (no
aliasing on *any* thread).

6d7e86d099 fix MIPS target
I ignored AtomicU64 methods on MIPS target
because libgcc doesn't implement MIPS32 64-bit atomic operations.
Otherwise it would cause link failure.

843c5e6308 std: Small cleanup and test improvement
This weeds out a bunch of warnings building stdtest on windows, and it also adds
a check! macro to the io::fs tests to help diagnose errors that are cropping up
on windows platforms as well.

301ff0c2df Remove two allocations from spawning a green task
Two unfortunate allocations were wrapping a proc() in a proc() with
GreenTask::build_start_wrapper, and then boxing this proc in a ~proc() inside of
Context::new(). Both of these allocations were a direct result from two
conditions:

1. The Context::new() function has a nice api of taking a procedure argument to
   start up a new context with. This inherently required an allocation by
   build_start_wrapper because extra code needed to be run around the edges of a
   user-provided proc() for a new task.

2. The initial bootstrap code only understood how to pass one argument to the
   next function. By modifying the assembly and entry points to understand more
   than one argument, more information is passed through in registers instead of
   allocating a pointer-sized context.

This is sadly where I end up throwing mips under a bus because I have no idea
what's going on in the mips context switching code and don't know how to modify
it.

56080c4767 Implement clone() for TCP/UDP/Unix sockets
This is part of the overall strategy I would like to take when approaching
issue #11165. The only two I/O objects that reasonably want to be "split" are
the network stream objects. Everything else can be "split" by just creating
another version.

The initial idea I had was the literally split the object into a reader and a
writer half, but that would just introduce lots of clutter with extra interfaces
that were a little unnnecssary, or it would return a ~Reader and a ~Writer which
means you couldn't access things like the remote peer name or local socket name.

The solution I found to be nicer was to just clone the stream itself. The clone
is just a clone of the handle, nothing fancy going on at the kernel level.
Conceptually I found this very easy to wrap my head around (everything else
supports clone()), and it solved the "split" problem at the same time.

The cloning support is pretty specific per platform/lib combination:

* native/win32 - uses some specific WSA apis to clone the SOCKET handle
* native/unix - uses dup() to get another file descriptor
* green/all - This is where things get interesting. When we support full clones
              of a handle, this implies that we're allowing simultaneous writes
              and reads to happen. It turns out that libuv doesn't support two
              simultaneous reads or writes of the same object. It does support
              *one* read and *one* write at the same time, however. Some extra
              infrastructure was added to just block concurrent writers/readers
              until the previous read/write operation was completed.

I've added tests to the tcp/unix modules to make sure that this functionality is
supported everywhere.

99582f8884 std: Hardcode pthread constants and structures
This allows for easier static initialization of a pthread mutex, although the
windows mutexes still sadly suffer.

Note that this commit removes the clone() method from a mutex because it no
longer makes sense for pthreads mutexes. This also removes the Once type for
now, but it'll get added back shortly.

b02b5cdcf4 Retry on EINVAL from pthread_attr_setstacksize()
Enforce that the stack size is > RED_ZONE + PTHREAD_STACK_MIN.  If the
call to pthread_attr_setstacksize() subsequently fails with EINVAL, it
means that the platform requires the stack size to be a multiple of the
page size.  In that case, round up to the nearest page and retry.

Fixes #11694.

ae2a5ecbf6 handle zero-size allocations correctly
The `malloc` family of functions may return a null pointer for a
zero-size allocation, which should not be interpreted as an
out-of-memory error.

If the implementation does not return a null pointer, then handling
this will result in memory savings for zero-size types.

This also switches some code to `malloc_raw` in order to maintain a
centralized point for handling out-of-memory in `rt::global_heap`.

  a `let` initializer, where we default to the innermost block. Rules
  are documented in the code, but not in the manual (yet).
  See new test run-pass/cleanup-value-scopes.rs for examples.
- Refactors Datum to better define cleanup roles.
- Refactor cleanup scopes to not be tied to basic blocks, permitting
  us to have a very large number of scopes (one per AST node).
- Introduce nascent documentation in trans/doc.rs covering datums and
  cleanup in a more comprehensive way.
