This is all purely fallout of getting the previous commit to compile.

It is often convenient to have forms of weak linkage or other various types of
linkage. Sadly, just using these flavors of linkage are not compatible with
Rust's typesystem and how it considers some pointers to be non-null.
As a compromise, this commit adds support for weak linkage to external symbols,
but it requires that this is only placed on extern statics of type `*T`.
Codegen-wise, we get translations like:
// rust code
extern {
#[linkage = "extern_weak"]
static foo: *i32;
}
// generated IR
@foo = extern_weak global i32
@_some_internal_symbol = internal global *i32 @foo
All references to the rust value of `foo` then reference `_some_internal_symbol`
instead of the symbol `_foo` itself. This allows us to guarantee that the
address of `foo` will never be null while the value may sometimes be null.
An example was implemented in `std::rt::thread` to determine if
`__pthread_get_minstack()` is available at runtime, and a test is checked in to
use it for a static value as well. Function pointers a little odd because you
still need to transmute the pointer value to a function pointer, but it's
thankfully better than not having this capability at all.
std: Move unstable::stack to rt::stack2014-02-23T09:47:08+00:00Brian Andersonbanderson@mozilla.com2014-02-17T05:37:12+00:00urn:sha1:db111846b58253c723750be280a478ed7d27d879std: Add init and uninit to mem.

glibc >= 2.15 has a __pthread_get_minstack() function that returns
PTHREAD_STACK_MIN plus however many bytes are needed for thread-local
storage. Use it when it's available because just PTHREAD_STACK_MIN is
not enough in applications that have big thread-local storage
requirements.
Fixes #6233.
Retry on EINVAL from pthread_attr_setstacksize()2014-01-31T12:47:25+00:00Ben Noordhuisinfo@bnoordhuis.nl2014-01-28T12:21:31+00:00urn:sha1:b02b5cdcf42b4fe6b1e3ebe56ad0cd43fd907489
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.
Removing do keyword from libstd and librustc2014-01-29T14:15:41+00:00Scott Lawrencebytbox@gmail.com2014-01-27T03:42:26+00:00urn:sha1:25e7e7f8076d879f824f013faa6f7470e69c818bUppercase numeric constants2014-01-25T08:38:25+00:00Chris Wonglambda.fairy@gmail.com2014-01-25T07:37:51+00:00urn:sha1:988e4f0a1c2802921375271bdc19f03650c024d2
The following are renamed:
* `min_value` => `MIN`
* `max_value` => `MAX`
* `bits` => `BITS`
* `bytes` => `BYTES`
Fixes #10010.
