c46e0d965b windows/registry: do not generate unaligned loads 
Byte slices aren't necessarily aligned, which means casting them to
integer types and dereferencing may result in an unaligned load. This
is mostly fine on Intel but isn't necessarily fine on other platforms.
Any good compiler will generate optimal code for the platform using the
pattern of this commit.

a5b02f93d8 windows: add "generate" build tag 
cmd/go supports the "generate" build tag as of CL 175983. Add it to the
files which are just used for generating errors and syscall wrappers.

Also see golang/go#31920

f6cff0780e windows/registry: improve ReadSubKeyNames permissions 
The existing implementation requires QUERY_VALUE and ENUMERATE_SUB_KEYS permissions to enumerate
subkeys, so, using registry key name limits, Stat function could be excluded
from methods body and improved method requires only ENUMERATE_SUB_KEYS permission

Registry elements size limits described there:

042a8f53ce windows: add NewLazySystemDLL and use it in zsyscall_windows.go 
If we want new secure DLL approach to be adopted, we should make
conversion as simple as possible to explain and implement.
I think that replacing

syscall.NewLazyDLL(...) -> windows.NewLazySystemDLL(...)

is easier than

syscall.NewLazyDLL(...) -> &windows.LazyDLL{Name: ..., System: true}

So I propose we introduce convenience function NewLazySystemDLL.

$GOROOT/src/mksyscall_windows.go changes in the following CL.
