Regression tests for #24161 use a macro to conditionally compile some
stub definitions. The macro tests that the minimum macOS version is
less than 10.12.
We get duplicate definitions when building this test with
CGO_CFLAGS=-mmacosx-version-min=10.x where 10.x < 10.12. With this
change, we use a different macro, __MAC_OS_X_VERSION_MAX_ALLOWED__,
which tests the SDK version instead of the minimum macOS version. This
checks whether these definitions are present in headers.
After this change, 'go tool dist test cgo_test' should pass with
CGO_FLAGS=-mmacosx-version-min=10.10.

The test for issue 8945 was marked to only run on gccgo, but there was
no reason for that. It broke for gccgo using GCC 10, because GCC 10
defaults to -fno-common. Make the test run on gc, and split it into
test.go and testx.go to make it work with GCC 10.
The test for issue 9026 used two identical structs which GCC 10 turns
into the same type. The point of the test is not that the structs are
identical, but that they are handled in a particular order. So make
them different.

According to the documentation "When passing a pointer to a field in a
struct, the Go memory in question is the memory occupied by the field,
not the entire struct.". checkAddr states that this should also work
with type conversions, which is implemented in isType. However,
ast.StarExpr must be enclosed in ast.ParenExpr according to the go spec
(see example below), which is not considered in the checks.
Example:
// struct Si { int i; int *p; }; void f(struct I *x) {}
import "C"
type S {
p *int
i C.struct_Si
}
func main() {
v := &S{new(int)}
C.f((*C.struct_I)(&v.i)) // <- panic
}
This example will cause cgo to emit a cgoCheck that checks the whole
struct S instead of just S.i causing the panic "cgo argument has Go
pointer to Go pointer".
This patch fixes this situation by adding support for ast.ParenExpr to
isType and adds a test, that fails without the fix.
