At runtime startup it calls newproc from assembly code to start

As of CL 318629, 'go mod download' without arguments does not save
checksums for module source code. Without a checksum, 'go list' will
not report the location of the source code even if it is present, in
order to prevent accidental access of mismatched code.
Downloading an explicit module here also more clearly expresses the
intent of the test (“download this module and see where it is”), and
may be somewhat more efficient (since the test doesn't need source
code for the other modules in the build list).

'go mod download' without arguments is frequently used to populate the
module cache. It tends to fetch a lot of extra files (for modules in
the build list that aren't needed to build packages in the main
module). It's annoying when sums are written for these extra files.
'go mod download mod@version' will still write sums for specific
modules in the build list. 'go mod download all' still has the
previous behavior.
For now, all invocations of 'go mod download' still update go.mod and
go.sum with changes needed to load the build list (1.15 behavior).

The test harness waits for "ready" as a sign that the Go runtime has
installed its signal handler and is ready to be tested. But actually,
while LoadLibrary starts the loading of the Go runtime, it does so
asynchronously, so the "ready" sign is potentially premature and
certainly racy. However, all exported cgo entry points make a call to
_cgo_wait_runtime_init_done which waits for that asynchronous
initialization to complete. Therefore, this commit fixes the test to
call into the exported "Dummy" cgo function before emitting the "ready"
sign, so that we're sure the Go runtime is actually loaded.

The general idea is that we now export/import typeparams, typeparam
lists for generic types and functions, and instantiated types
(instantiations of generic types with either new typeparams or concrete
types).
This changes the export format -- the next CL in the stack adds the
export versions and checks for it in the appropriate places.
We always export/import generic function bodies, using the same code
that we use for exporting/importing the bodies of inlineable functions.
To avoid complicated scoping, we consider all type params as unique and
give them unique names for types1. We therefore include the types2 ids
(subscripts) in the export format and re-create on import. We always
access the same unique types1 typeParam type for the same typeparam
name.
We create fully-instantiated generic types and functions in the original
source package. We do an extra NeedRuntimeType() call to make sure that
the correct DWARF information is written out. We call SetDupOK(true) for
the functions/methods to have the linker automatically drop duplicate
instantiations.
Other miscellaneous details:
- Export/import of typeparam bounds works for methods (but not
typelists) for now, but will change with the typeset changes.
- Added a new types.Instantiate function roughly analogous to the
types2.Instantiate function recently added.
- Always access methods info from the original/base generic type, since
the methods of an instantiated type are not filled in (in types2 or
types1).
- New field OrigSym in types.Type to keep track of base generic type
that instantiated type was based on. We use the generic type's symbol
(OrigSym) as the link, rather than a Type pointer, since we haven't
always created the base type yet when we want to set the link (during
types2 to types1 conversion).
- Added types2.AsTypeParam(), (*types2.TypeParam).SetId()
- New test minimp.dir, which tests use of generic function Min across
packages. Another test stringimp.dir, which also exports a generic
function Stringify across packages, where the type param has a bound
(Stringer) as well. New test pairimp.dir, which tests use of generic
type Pair (with no methods) across packages.
- New test valimp.dir, which tests use of generic type (with methods
and related functions) across packages.
- Modified several other tests (adder.go, settable.go, smallest.go,
stringable.go, struct.go, sum.go) to export their generic
functions/types to show that generic functions/types can be exported
successfully (but this doesn't test import).

If a filepath.WalkFunc returns filepath.SkipDir when invoked on a
non-directory file, it skips the remaining files in the containing
directory.¹
CL 276272 accidentally added a code path that triggers this behavior
whenever filepath.Walk reaches a non-directory file that begins with
a dot, such as .gitattributes or .DS_Store, causing findGorootModules
to return early without finding any modules in GOROOT. Tests that use
it ceased to provide test coverage that the tree is tidy.
Add an explicit check for info.IsDir in the 5 places that intend to
use filepath.SkipDir to skip traversing that directory. Even paths
like GOROOT/bin and GOROOT/pkg which are unlikely to be anything but
a directory are worth checking, since the goal of moddeps is to take
a possibly problematic GOROOT tree as input and detect problems.
While the goal of findGorootModules is to find all modules in GOROOT
programmatically (in case new modules are added or modified), there
are 4 modules now that are quite likely to exist, so check for their
presence to avoid similar regressions. (It's not hard to update this
test if a well-known GOROOT module is removed or otherwise modified;
but if it becomes hard we can simplify it to check for a reasonable
number of modules instead.)
Also fix the minor skew that has crept in since the test got disabled.
¹ This wasn't necessarily an intentional design decision, but it was
found only when Go 1.4 was already out. See CL 11690 for details.

When declaring anonymous parameters, use the syntax.Field's Pos
directly rather than its Type field's Pos. When the type expression is
a qualified identifier (i.e., SelectorExpr), its Pos returns the
position of the dot, whereas we typically declare the anonymous
parameter at the starting position of the type. (We could equivalently
use syntax.StartPos(field.Type), but we already have this as
field.Pos().)

When reporting a "cannot import package as init" error, we can't rely
on s.LocalPkgName being non-nil, as the original package's name may
already be nil.

Followup to previous commit that extended test/run.go to run more
tests with -G=3. This CL updates a handful of easy test cases for
types2 compatibility.

The parser accepted embedded elements but the first term
of an element had to be a ~-term or a type name. This CL
fixes that.

issue46234.go expects an error output "segmentation violation",
which is UNIX-specific. Check for "nil pointer dereference"
instead, which is emitted by the Go runtime and should work on all
platforms.

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.
