Ian Lance Taylor bbe5da4260 cmd/compile, syscall: add //go:uintptrescapes comment, and use it ... This new comment can be used to declare that the uintptr arguments to a function may be converted from pointers, and that those pointers should be considered to escape. This is used for the Call methods in dll_windows.go that take uintptr arguments, because they call Syscall. We can't treat these functions as we do syscall.Syscall, because unlike Syscall they may cause the stack to grow. For Syscall we can assume that stack arguments can remain on the stack, but for these functions we need them to escape. Fixes #16035.
