Beyond the usual updating of version strings, re-running `go generate`, and updating the patches for the linker, we needed extra changes. First, the linker started being stricter about which packages are allowed to linkname runtime names by import path. Stop obfuscating import paths in runtimeAndLinknamed. Second, the compiler's intrinsics code adds an "add" function much like the existing "addF", so tweak the regular expression. Third, note that there is a new runtimeAndDeps windows-only package, which we find thanks to the recent improvement to cover many platforms. Fourth, the code around magic numbers in the runtime has changed, so rewrite the code which patches it via go/ast. Fixes #990.
