runtime: complete defer handling in CgocallBackDone

    When C code calls a Go function, it actually calls a function
    generated by cgo. That function is written in Go, and, among other
    things, it calls the real Go function like this:
            CgocallBack()
            defer CgocallBackDone()
            RealGoFunction()
    The deferred CgocallBackDone function enters syscall mode as we return
    to C. Typically the C function will then eventually return to Go.

    However, in the case where the C function is running on a thread
    created in C, it will not return to Go. For that case we will have
    allocated an m struct, with an associated g struct, for the duration
    of the Go code, and when the Go is complete we will return the m and g
    to a free list.

    That all works, but we are running in a deferred function, which means
    that we have been invoked by deferreturn, and deferreturn expects to
    do a bit of cleanup to record that the defer has been completed. Doing
    that cleanup while using an m and g that have already been returned to
    the free list is clearly a bad idea. It was kind of working because
    deferreturn was holding the g pointer in a local variable, but there
    were races with some other thread picking up and using the newly freed g.
    It was also kind of working because of a special check in freedefer;
    that check is no longer necessary.

    This patch changes the special case of releasing the m and g to do the
    defer cleanup in CgocallBackDone itself.

    This patch also checks for the special case of a panic through
    CgocallBackDone. In that special case, we don't want to release the m
    and g. Since we are returning to C code that was not called by Go
    code, we know that the panic is not going to be caught and we are
    going to exit the program. So for that special case we keep the m and
    g structs so that the rest of the panic code can use them.

Fix expand_builtin_atomic_fetch_op for pre-op (PR80902)

__atomic_add_fetch adds a value to some memory, and returns the result.
If there is no direct support for this, expand_builtin_atomic_fetch_op
is asked to implement this as __atomic_fetch_add (which returns the
original value of the mem), followed by the addition.  Now, the
__atomic_add_fetch could have been a tail call, but we shouldn't
perform the __atomic_fetch_add as a tail call: following code would
not be executed, and in fact thrown away because there is a barrier
after tail calls.

runtime: make NumGoroutine wait for system goroutines to register

    In libgo system goroutines register themselves after they start.
    That means that there is a small race between the goroutine being
    seen by the scheduler and the scheduler knowing that the goroutine
    is a system goroutine. That in turn means that runtime.NumGoroutines
    can overestimate the number of goroutines at times.

    This patch fixes the overestimate by counting the number of system
    goroutines waiting to start, and pausing NumGoroutines until those
    goroutines have all registered.

    This is kind of a lot of mechanism for this not very important
    problem, but I couldn't think of a better approach.

    The test for this is TestNumGoroutine in runtime/proc_test.go.

runtime: don't assume that _ = *s will panic if s is nil

    With the gc toolchain apparently
            var s *string
            _ = *s
    is enough to panic with a nil pointer dereference. The gccgo compiler
    will simply discard the dereference, which I think is a reasonable and
    acceptable optimization. Change the tests to use an exported variable
    instead. The tests are not currently run, but they will be with a

runtime: change some stack fields to uintptr

    Because of how gccgo implements cgo calls, the code in dropm may not
    have any write barriers.  As a step toward implementing that, change
    the gcstack, gcnextsegment, and gcnextsp fields of the g struct to
    uintptr, so that assignments to them do not require write barriers.
    The gcinitialsp field remains unsafe.Pointer, as on 32-bit systems
    that do not support split stack it points to a heap allocated space
    used for the goroutine stack.

    The test for this is runtime tests like TestCgoCallbackGC, which are

runtime: avoid write barriers when calling deferred function

    Calling a deferred function currently requires changing from a uintptr
    to the function code to a Go function value. That is done by setting
    the value of a func local variable using unsafe.Pointer. The local
    variable will always be on the stack. Adjust the code that sets the
    local variable to avoid generating a write barrier.

    A write barrier is never needed here. Also, for deferreturn, we must
    avoid write barriers entirely when called from a cgo function; that
    requires more than just this, but this is a start.

    The test for this is runtime tests that use the go tool; these are not
    currently run, but they will be in the future.
