2b5306a94b Add missing clobbers to context switching
This only shows in release mode, the compiler tries to preserve some
value in rdi, but that gets replaced inside the fiber. This would not
happen in the C calling convention, but in these normal Zig functions,
it can happen.

806214797a std.Io: rename go to asyncDetached
it's a better name because it's more descriptive, not a reference, and
hints that it is less common than async

c8950b5dd5 EventLoop: fix std.Io.Condition implementation
1. a fiber can't put itself on a queue that allows it to be rescheduled
 2. allow the idle fiber to unlock a mutex held by another fiber by
    ignoring reschedule requests originating from the idle fiber

708bac1a57 EventLoop: fix futex usage
How silly of me to forget that the kernel doesn't implement its own API.
The scheduling is not great, but at least doesn't deadlock or hammer.

507f973b5e EventLoop: get file operations working
Something is horribly wrong with scheduling, as can be seen in the
debug output, but at least it somehow manages to exit cleanly...

2f2019645c EventLoop: move context after the async closure
This avoids needing to store more sizes and alignments.  Only the result
alignment needs to be stored, because `Fiber` is at a fixed zero offset.

dfbf68e5fa EventLoop: fix incorrect alignment panic
When the previous fiber did not request to be registered as an awaiter,
it may not have actually been a full blown `Fiber`, so only create the
`Fiber` pointer when needed.
