Distinguish the gcshape of all top-level instantiated type from normal
concrete types, even if they have the exact same underlying "shape",
because in a function instantiation, any method call on this type arg
will be a generic method call (requiring a dictionary), rather than a
direct method call on the underlying type (no dictionary).
So, we add the instshape prefix to the gcshape name for instantiated
types, and we make it a defined type with that name.

When instantiating a generic type or function with multiple type
arguments, we need to represent an index expression with multiple
indexes in the AST. Previous to this CL this was done with a new
ast.ListExpr node, which allowed packing multiple expressions into a
single ast.Expr. This compositional pattern can be both inefficient and
cumbersome to work with, and introduces a new node type that only exists
to augment the meaning of an existing node type.
By comparison, other specializations of syntax are given distinct nodes
in go/ast, for example variations of switch or for statements, so the
use of ListExpr was also (arguably) inconsistent.
This CL removes ListExpr, and instead adds a MultiIndexExpr node, which
is exactly like IndexExpr but allows for multiple index arguments. This
requires special handling for this new node type, but a new wrapper in
the typeparams helper package largely mitigates this special handling.

This change concentrates the creation is lazily instantiated types
in one place (InstantiateLazy). This should also make it easier to
replace the implementation of lazily instantiated types (e.g. getting
rid of instance types).

Allow Checker.Instantiate to work with a nil *Checker receiver
(for now). This opens the door to passing in a *Checker at all
times.
Also, added a verify flag to Instantiate, InstantiateLazy, and
instance, to be able to control if constraint satisfaction should
be checked or not.
Removed types2.Instantiate.
For #47103.
