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
anyway.

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.

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.

This reverts a part of 365e40b. While it is not legal to clobber
the output register, it is legal and necessary to do this for inputs,
since we do not preserve them, and LLVM could have decided to
reuse them.
Thanks to @Amanieu for discovering this.
