Defn node to the nodes that reference it, and update the Defn fields of
the copied name nodes at the time that we create the new copy of the

This CL configures the parser to always accept 1.18 syntax
(type parameters, type instantiations, interface elements),
even when -lang is set to an earlier release.
Instead, the type checker looks for 1.18 operations and
complains if the language version is set to an earlier
release.
Doing these checks during type checking is necessary because it
it is possible to write "generic" code using pre-1.18 syntax;
for instance, an imported generic function may be implicitly
instantiated (as in imported.Max(2, 3)), or an imported constraint
interface may be embedded in an "ordinary" interface.

Issues 47713 and 47877 were both due to problems with the names used for
instantiated functions/methods, which must be in sync with the names
used by types2.
- Switched to using NameString() for writing out type arguments in
instantiation names. This ensures that we are always adding the
package to type names even for the local package. Previously, we were
explicitly adding the package name for local packages, but that
doesn't handle the case when the local type is embedded inside a
pointer or slice type. By switching to NameString(), we fix#47713.
- types1 and types2 write out 'interface {' differently (vs.
'interface{') and we were already handling that. But we needed to add
similar code to handle 'struct {' vs 'struct{'. This fixes issue
#47877.
While fixing these bugs, I also moved some duplicated code (which
include some of the changes above) into a common function addTargs(). I
also moved InstType() name to subr.go, and renamed: MakeInstName ->
MakeFuncInstSym and MakeDictName -> MakeDictSym.
Also removed a couple of ".inst..inst." prefix checks which are
irrelvant now, since we don't add ".inst." anymore to function
instantiations.

the array type when creating an OpAddr while processing the loop that
initializes the map from the arrays. The pointer type does not inherit

This causes values created through reflect of types that should be
equal to compare unequal because the noalg and alg type might be

CL 324890 turned on register ABI by default on ARM64, causing neither
live.go nor live_regabi.go is run on ARM64.
This CL enables live_regabi.go test for ARM64.

This is used within Google's internal code repo, so getting it working
is a pre-req for enabling -G=3 by default.

We need an extra case in convertToDictionary. In the case of an operand
which is an interface and converting to an empty interface, we don't
want to get the run-time type from the dictionary (which would be the
run-time type of the interface). We want to do a type-assert to the
empty interface.

Currently, for hidden closures, we always push them to compile queue
during typechecking. If the hidden closure is discarded from the outer
function body during deadcode, any desugaring phase after deadcode won't
be applied to the closure. Thus, some un-expected OPs are passed to
downstream passes, which they can't handle, the compiler goes boom!
To fix this, we keep track of discarded hidden closures during deadcode
pass, and won't compile them then.

We use "build" for tests in the main package with a main function.
We use "compile" for tests that are not in the main package.
