I have left the Diag calls in place where I believe Ctxt.Cursym != nil which means this CL is not the improvement I had hoped for. However it is now safe to call Exitf whereever you are in the linker, which makes it easier to reason about some code.

Use SETcc instructions instead of Jcc to generate boolean values. This generates shorter, jump-free code, which may in turn enable other peephole optimizations.

readyExecute passes a closure to mcall that captures an argument to readyExecute. Since mcall is marked noescape, this closure lives on the stack of the calling goroutine. However, the closure puts the calling goroutine on the run queue (and switches to a new goroutine). If the calling goroutine gets scheduled before the mcall returns, this stack-allocated closure will become invalid while it's still executing. One consequence of this we've observed is that the captured gp variable can get overwritten before the call to execute(gp), causing execute(gp) to segfault. Fix this by passing the currently captured gp variable through a field in the calling goroutine's g struct so that the func is no longer a closure. To prevent problems like this in the future, this change also removes the go:noescape annotation from mcall. Due to a compiler bug, this will currently cause a func closure passed to mcall to be implicitly allocated rather than refusing the implicit allocation. However, this is okay because there are no other closures passed to mcall right now and the compiler bug will be fixed shortly. Fixes #10428.

Previously we started the Go runtime from a JNI function call, which eventually called the program's main function. Now the runtime is initialized by an ELF initialization function as a c-shared library, and the program's main function is not called. So now we export main so it can be called from JNI. This is necessary for all-Go apps because unlike a normal shared library, the program loading the library is not written by or known to the programmer. As far as they are concerned, the .so is everything. In fact the same code is compiled for iOS as a normal Go program.

Instead of only checking packages that are already listed in pkgDeps, apply deps checks to all standard library packages. To avoid slowing testing down too much, instead of running "go list std" in a subprocess like cmd/api or cmd/dist, this test manually walks the GOROOT src directory to enumerate packages. Timings on an HP Z620 using linux/amd64: short full before 0.092s 4.880s after 0.137s 5.104s Additionally, a handful of packages that were previously unchecked are now listed, along with their current dependencies. These should probably eventually be moved elsewhere and assigned appropriate allowable-dependency sets. For now, they've been grandfathered in by simply assigning them their current dependencies, so that followup CLs can review them individually as appropriate. Fixes #10475.
