This CL moves two bits of related code from order.go to escape analysis: 1. The recognition of "unsafe uintptr" arguments passed to syscall-like functions. 2. The wrapping of go/defer function calls in parameter-free function literals. As with previous CLs, it would be nice to push this logic even further forward, but for now escape analysis seems most pragmatic. A couple side benefits: 1. It allows getting rid of the uintptrEscapesHack kludge. 2. When inserting wrappers, we can move some expressions into the wrapper and escape analyze them better. For example, the test expectation changes are all due to slice literals in go/defer calls where the slice is now constructed at the call site, and can now be stack allocated.
