cmd/compile: fix deadlock in (Named).load For lazy import resolution, there's reentrancy issue with (Named).load method, when "t.resolve(t)" can lead us to the same named type, thus (Named).load is called recursively, causing the deadlock. The main problem is that when instantinate a type, we calculate the type hashing, including TParams. Calling t.TParams().Len() triggers the reentrancy call to "(Named).load". To fix this, just not checking TParams().Len() if we are hashing.
