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
extra checking).
Added a bunch of these test cases to 13.go, which now passes.

This CL changes fixedbugs/issue30862.go into a "runindir" test so that
it can use '-goexperiment fieldtrack' and test that //go:nointerface
works with cmd/compile. In particular, this revealed that -G=3 and
unified IR did not handle it correctly.
This CL also fixes unified IR's support for //go:nointerface and adds
a test that checks that //go:nointerface, promoted methods, and
generics all interact as expected.
Updates #47045.

Removed a case in transformCall() where we were setting a type on n,
which isn't needed, since noder2 already set the type of n. More
importantly, we are losing information, since the type of the results
may be a shape type, but the actual type of call is the known type
from types2, which may be a concrete type (in this case Zero[MyInt]).
That concrete type will then be used correctly if the concrete result is
converted to an interface.
If we are inlining the call to Zero[MyInt], we need to add an implicit
CONVNOP operation, since we are going to use the result variable
directly, which has a shape type. So, add an implicit CONVNOP to
remember that the known type is the concrete type.
Also cleaned up 14.go a bit, so it is more understandable. Renamed type
T to AnyInt, since T is used elsewhere as a type parameter. Reformatted
Zero function and added a comment.

This CL includes multiple test cases that exercise unique failures
with -G=3 mode that did not affect unified IR mode. Most of these were
found over a period of about 3 hours of manual experimentation.
Thanks to Cuong Manh Le for test cases 11 and 12.
Updates #46704.
