Gerd Zellweger 5849a2d330 Replace simd with packed_simd
The simd crate no longer builds, as of Rust 1.33 nightly, due to the 
removal of compiler features that it depends on. packed_simd is the 
recommended replacement.

edef df7f261ca6 Expose unsafe_unwrap
This at least ensures we don't have to needlessly leak generators in the
tests, and covers similar use cases for consumers of libfringe.

edef d49557a55a Require Stack to be 'static
Our strategy of leaking the Stack to ensure safety is only effective if
the lifetime of the underlying stack memory is controlled by the
destructor of the Stack. We don't add this bound to unsafe_new, so that
users who wish to provide the necessary guarantees themselves can do so.

edef 4813dd7411 Leak the stack if it's unsafe to drop it
We can't free the stack before the generator has returned, or been
unwound. Without unwinding, the only safe course of action is to leak

edef dcde4fe920 Don't use unsafe for the forget_yielded test
Now that the Send bound is gone, we can simply use a Cell instead of a
raw pointer.

edef 661872f725 Don't implement Send at all
On hosted platforms, libstd allows safely borrowing values from TLS with
'thread lifetime and without a Sync bound. As a result, we can't
guarantee that sending a generator across threads won't create dangling
references or data races. In freestanding environments, the notion of
thread-safety is likely to be defined by the consumer of libfringe,
so our Send bounds and implementation are unlikely to be meaningful

edef 19ec5ef45b Make the passed Yielder borrow immutable [breaking-change]
Yielder::suspend only requires an immutable reference, and allowing
mem::replace on the yielder isn't very useful.

Amanieu d'Antras f7f209c1eb Add proper CFI annotations to the inline asm
This ensures that gdb is able to generate a correct backtrace when
stopped at any instruction in the inline asm.

It also makes backtraces accessible to tools that only track frame
pointer chains, like perf or dtrace.

whitequark 231bc3cc46 Yielder: use Cell internally to allow suspending via multiple borrows.
The use case is as follows: let's say I have a scheduler that uses
libfringe for context switching. A single thread may open several
sockets, each of which presents a std::io::Read interface, and
waiting in Read::read requires having a reference to the yielder
inside the socket.

This could be worked around with RefCell in the API consumer, but
there is no real reason to not implement it in libfringe.

whitequark 491af39fc9 Radically simplify stack linking.
This commit:

  * Gets rid of 2nd init trampoline.
  * Gets rid of any custom CFI, instead using the standard CFI
    for target prologue.
  * Makes backtraces accessible to tools that only track frame
    pointer chains, like perf or dtrace.
  * Keeps the performance at the exact same level.
