Change all instantiated methods to being functions again. We found that
this is easier for adding the dictionary argument consistently. A method
wrapper will usually be added around the instantiation call, so that
eliminate the inconsistency in the type of the top-level method and the
the associated function node type.

This CL extends types2 with package height information, styled after
the way it works already in cmd/compile:
- A new NewPackageHeight entry point for constructing packages with
explicit height information, and a corresponding Height accessor
method.
- The types2 importer is updated to provide package height for
imported packages.
- The types2 type checker sets height based on imported packages.
- Adds an assertion to irgen to verify that types1 and types2
calculated the same height for the source package.
- Func.less's ordering incorporates package height to match
types.Sym.less and is generalized to object.less.
- sortTypes (used for sorting embedded types) now sorts defined types
using object.less as well.

Currently the exporter uses types.IsDotAlias(n.Sym()) to recognize
that n is a type alias, but IsDotAlias is actually meant for
recognizing aliases introduced by dot imports. Translated to go/types,
the current logic amounts recognizing type aliases as if by:
var n *types.TypeName
typ, ok := n.Pkg().Scope().Lookup(n.Name()).Type().(*types.Named)
isAlias := !ok || typ.Obj().Pkg() != n.Pkg() || typ.Obj().Name() != n.Name()
But we can instead just check n.Alias() (eqv. n.IsAlias() in
go/types). In addition to being much simpler, this is also actually
correct for recognizing function-scoped type declarations (though we
don't currently support those anyway, nor would they go through this
exact code path).
To avoid possible future misuse of IsDotAlias, this CL also inlines
its trivial definition into its only call site.
Passes toolstash -cmp, also w/ -gcflags=all=-G=3.

Some uses of crosscall2 did not work on ppc64le and probably
aix-ppc64. In particular, if there was a main program compiled
with -buildmode=pie and used a plugin which invoked crosscall2,
then failures could occur due to R2 getting set incorrectly along the
way. The problem was due to R2 being saved on the caller's
stack; it is now saved on the crosscall2 stack. More details can be
found in the issue.
This adds a testcase where the main program is built with pie
and the plugin invokes crosscall2.
This also changes the save of the CR bits from MOVD to MOVW as
it should be.

The Context.ImportDir method in the go/build package sets Package.Root
to $GOPATH, if a package is inside a GOPATH workspace. The
loadPackageData function keeps this value even when modules are enabled.
Override Package.Root when modules are enabled, instead of just set its
value when Context.ImportDir was unable to set it.
Add a regression test.

Currently all script tests use the UNIX path separator with the cd
command, causing the PWD environment variable to have the incorrect path
separator on Windows.
Call filepath.FromSlash on the cd command argument.
Update the testdata/script/README to document that the cd argument must
use slashes.

To reproduce this issue, a test must use the cd command followed by a
stdout or stderr command containing the pattern $PWD.

Especially with typesets, we should be able to fully represent a
typeparam bound as just another type (actually an interface type).
Change the representation of a typeparam in types1 to include a bound,
which is just a type. Changed the signature for NewTypeParam() to take a
sym, and not a package, since we always set the sym (name) of the
typeparam when creating it. No need for an extra pkg field in Typeparam.
Also added index field in the types1 representation of typeparam. This
is especially needed to correctly export the typeparam, and re-import it
as a types2 type (which requires the index to be set correctly).

In the deadcode path we mark runtime.unreachableMethod symbol,
which is a special symbol used for redirecting unreachable
methods. Currently this code is conditioned on not -linkshared.
This is wrong. It should be marked with -linkshared mode as well.
In fact, -linkshared should only affect the entry symbol. Change
the code accordingly.

We redirect references to unreachable methods to
runtime.unreachableMethod. We choose to use ABIInternal symbol
for this, because runtime.unreachableMethod is a defined Go
function.
When linking against shared libraries, and ABI wrappers are not
enabled, the imported function symbols are all ABI0 and aliased
to ABIInternal. We need to resolve ABI alias in this case.

Previously, we were converting an instantitated method to a function, by
moving the receiver arg to the regular args, etc. But that made the type
of the method signature inconsistent with the signature on the method
fields, which leads to some problems with more complex programs with
instantiations. And things work fine if we leave the instantiated method
as a method. So, make the change to keep instantiated methods as real
methods (until they are transformed much later in the compiler).

It is unclear what the future holds for the go line in go.mod files.
Perhaps at some point we will switch to semver numbering.
Perhaps at some point we will allow specifying minor versions
or even betas and release candidates.
Those kinds of changes are difficult today because the go line
is parsed in dependency modules, meaning that older
versions of the Go toolchain need to understand newer go lines.
This CL makes that case - parsing a go line in a dependency's
go.mod file - a bit more lax about how to find the version.
It allows a leading v and any trailing non-digit-prefixed string
after the MAJOR.MINOR section.
There are no concrete plans to make use of any of these changes,
but if in the future we want to make them, having a few Go releases
under out belt that will accept the syntax in dependencies will
make any changes significantly easier.
