Now that the pointer identity for a *Named type doesn't change
anymore when going from lazy instantiated to actually instantiated
(= expanded) state, expand() only needs to be called when we deal
with *Named types and only if we care about a *Named type's internals.
Remove the expand function and respective calls for all types and
replace with specific t.expand() method calls where t is a *Named.

in the importer to deal with unions and non-method members of an

In the cases where we do an early call to typecheckaste() in noder to
expose CONVIFACE nodes, we need a preceding call to transformArgs().
This is needed to allow typecheckaste() to run correctly, in the case of
f(g()), where g has multiple return values.
I also cleaned up the code a bit and commented the code in Call(), and
we do the call to typecheckaste() in several more cases.
In stencil.go:stencil(), I moved the transformCall earlier for the
OCALLMETH/ODOTMETH case, just as I did in my previous CL for
OCALL/OFUNCINST. By doing this, transformArgs no longer needs to deal
with the extra dictionary args. Therefore, I was able to simply
transformArgs() to look like typecheckargs() again, and make use of
RewriteMultiValue directly.

Writing CL 333629 clarified my thinking about the behavioral changes
associated with lazy loading. There are really two interrelated
changes — graph pruning, and lazy loading proper — that are both made
possible by the added redundancy in the go.mod file.
(I had initially approached the whole cluster of features as “lazy
loading” because that was the starting point for the design. Graph
pruning came into the picture when we looked at how to bound the
worst-case behavior of lazy loading, but it is really the more
important of the two aspects of the design.)
Note that this change adds links to doc anchors added in CL 333629.

The one remaining TODO that really needs to be done is generating

Do the transformCall using the original types2-derived type of the call

interface conversions to an interface with shapes in the one case of a
full-instantiated generic call. So, we do the transformCall() before
installing the shaped-based instantiation. transformCall() works
correctly even in the case of OCALL/FUNCINST.
Fixed two related bugs:
- Fixed case where we still were not correctly substituting the types
for a function instantiation.
- The type substituter needs to copy field flags while substituting in
tstruct.

So, we set a flag in (*irgen) that records when we are noding a

structured exception handlers. When LoadLibrary-ing DLLs that do this

In this case, we can't use an itab for doing a bound call, since we're
converting from an interface to an interface. We do a static or dynamic
type assert in new function assertToBound().
The dynamic type assert in assertToBound() is only needed if a bound is
parameterized. In that case, we must do a dynamic type assert, and
therefore need a dictionary entry for the type bound (see change in
getGfInfo). I'm not sure if we can somehow limit this case, since using
an interface as a type arg AND having the type bound of the type
arg be parameterized is a very unlikely case.
Had to add the TUNION case to parameterizedBy1() (which is only used for

CL 339396 allowed stack copying on entry to and during freedefer, but
this introduced a subtle bug: if d is heap-allocated, and d.link
points to a stack-allocated defer, stack copying during freedefer can
briefly introduce a stale pointer, which the garbage collector can
discover and panic about. This happens because d has already been
unlinked from the defer chain when freedefer is called, so stack
copying won't update stack pointers in it.
Fix this by making freedefer nosplit again and immediately clearing
d.link.
This should fix the longtest builders, which currently fail on
GOMAXPROCS=2 runtime -cpu=1,2,4 -quick in the TestDeferHeapAndStack
test.
This seems like the simplest fix, but it just deals with the subtlety
rather than eliminating it. Really, every call site of freedefer (of
which there are surprisingly many) has hidden subtlety between
unlinking the defer and calling freedefer. We could consolidate the
subtlety into each call site by requiring that they unlink the defer
and set d.link to nil before calling freedefer. freedefer could check
this condition like it checks that various other fields have already
been zeroed. A more radical option is to replace freedefer with
"popDefer", which would both pop the defer off the link and take care
of freeing it. There would still be a brief moment of subtlety, but it
would be in one place, in popDefer. Annoyingly, *almost* every call to
freedefer just pops the defer from the head of the G's list, but
there's one place when handling open-coded defers where we have to
remove a defer from the middle of the list. I'm inclined to first fix
that subtlety by only expanding open-coded defer records when they're
at the head of the defer list, and then revisit the popDefer idea.

This test made many requests over the same connection for 10
seconds, trusting that this will exercise the request cancelation
race from #41600.
Change the test to exhibit the specific race in a targeted fashion
with only two requests.
Updates #41600.

When static == false, missingMethod incorrectly continues with a nil
Func.
Also remove some unnecessary type names from typeterm_test.go, which was
done in the go/types port.

This is a port of CL 337354 to go/types, adjusted for the error
reporting API and to reposition a couple error messages in
issue47411.go2 (the go/types position is probably better).
A panic is also fixed in lookup.go when method lookup fails and static
== false. I'll send a fix for types2 in a separate CL.
For #47411
