These methods are sorely needed on readers and writers, and I believe that the
encoding story should be solved with composition. This commit adds back the
missed functions when reading/writing strings onto generic Readers/Writers.

This pull request fixes#11083. The problem was that recursive type definitions were not properly handled for enum types, leading to problems with LLVM's metadata "uniquing". This bug has already been fixed for struct types some time ago (#9658) but I seem to have forgotten about enums back then. I added the offending code from issue #11083 as a test case.
This patchset adds intrinsics similar to the to_[be|le][16|32|64] intrinsics but for going in the reverse direction, e.g. from big/little endian to host endian. Implementation wise they do exactly the same as the corresponding to_* functions but I think it anyway make sense to have them since using the to_* functions in the reverse direction is not entirely intuitive.
The first patch adds the intrinsics and the two following changes instances of bswap* to use the [to|from]_* intrinsics instead.
Running a rust program with `RUST_LOG=::help` no longer shows all the logging modules that are mentioned in the docs. These should be removed from the docs as they no longer do anything.
For libgreen, bookeeping should not be global but rather on a per-pool basis.
Inside libnative, it's known that there must be a global counter with a
mutex/cvar.
The benefit of taking this strategy is to remove this functionality from libstd
to allow fine-grained control of it through libnative/libgreen. Notably, helper
threads in libnative can manually decrement the global count so they don't count
towards the global count of threads. Also, the shutdown process of *all* sched
pools is now dependent on the number of tasks in the pool being 0 rather than
this only being a hardcoded solution for the initial sched pool in libgreen.
This involved adding a Local::try_take() method on the Local trait in order for
the channel wakeup to work inside of libgreen. The channel send was happening
from a SchedTask when there is no Task available in TLS, and now this is
possible to work (remote wakeups are always possible, just a little slower).
