This CL updates noder and typecheck to avoid a couple of instances of
redundant evaluation of type expressions:
1. When noding struct fields or parameter tuples, check for
syntax.Type reuse between adjacent fields and then reuse the
corresponding ir.Node type expression. It would perhaps be even better
to avoid re-noding the type expression too, but noder's days are
numbered anyway, so I'd rather be minimally invasive here.
2. When importing an empty interface, reuse the same cached empty
interface instance that is used for empty interfaces that appear in
source. This matches types2's behavior, which uses a single
types2.Interface instance for all empty interfaces.
These changes are motivated by making it possible to migrate from
typecheck to types2 while passing toolstash -cmp.
Updates #46208.

Add union support in types1, and allow exporting of unions, and
importing unions back into types1 and types2.
Added new test mincheck.go/mincheck.dir that tests that type lists (type
sets) are correctly exported/imported, so that types2 gives correct
errors that an instantiation doesn't fit the type list in the type param

In a late change to golang.org/cl/320609, while going back and forth
on the meaning of the boolean result value for "checkFlags", I got one
of the cases wrong. As a result, rather than testing both default
flags and -G=3, we were (redundanly) testing default flags and -G=0.
I ran into this because in my local dev tree, I'm using types2 even
for -G=0, and evidently one of the recent types2 CLs changed the error
message in fixedbugs/issue10975.go. Fortunately, there haven't been
any other regressions despite lacking test coverage.
So this CL cleans things up a bit:
1. Fixes that test to use -lang=go1.17, so types2 reports the old
error message again.
2. Renames "checkFlags" to "validForGLevel" so the boolean result is
harder to get wrong.
3. Removes the blanket deny list of all -m tests, and instead adds the
specific tests that are still failing. This effectively extends -G=3
coverage to another 27 tests that were using -m but already passing,
so we can make sure they don't regress again.
4. Adds a -f flag to force running tests even if they're in the deny
list, to make it easier to test whether they're still failing without
having to edit run.go.

Accept embedded interface elements of the form ~T or A|B and
treat them like type lists: for now the elements of a union
cannot be interfaces. Also, translate existing style "type"-
lists in interfaces into interface elements: "type a, b, c"
becomes a union element "~a|~b|~c" which in turn is handled
internally like a type list.
For now, "~" is still ignored and type lists are mapped to
Sum types as before, thus ensuring that all existing tests
work as before (with some minor adjustments).
Introduced a new Union type to represent union elements.
For now they don't make it past interface completion where
they are represented as a Sum type. Thus, except for printing
(and the respective tests) and substitution for interfaces,
the various type switches ignore Union types. In a next step,
we'll replace Sum types with union types and then consider
the ~ functionality as well.
Because union elements are no different from embedded interfaces
we don't need a separate Interface.types field anymore. Removed.

We have a value typecheck(3) that indicates that a node in a generic
function still needs transformation (via the functions in transform.go).
But it is not very desirable to export/import the value of typecheck(3).
So, I changed the stenciling code to just try to transform all relevant
node types during node copy. Almost all tranform functions were already
idempotent. I only had to add an extra if check before calling
transformAssign() in the OAS case. We still use the typecheck(3) in
noder to determine when higher-nodes have to delay transformation
because one or more of their args are delaying transformation.
Added new test mapsimp.go that required these tranformations after import.
As an additional change, export/import of OINDEX requires exporting the
type using w.exoticType() rather than w.typ(), in order to handle
generic functions. Since generic functions can have pre-transform
operations, the index operation can have a tuple type (multiple return
from a map lookup).
Added printing of imported function bodies in -W=3 debug mode.

For register ABI, we wrap deferred/go'd function with arguments
or results in an argumentless closure, so the runtime can call the
function without knowing how to marshal the arguments, or
reserving frame for arguments and results.
The wrapping mechanism works everywhere, regardless of whether the
register ABI is used. And wrapping will simplify the compiler and
runtime's implementation for defer and go calls. For example, the
compiler will not need to marshal arguments for defer/go calls,
the opendefer metadata will not need to contain argument
information, and _defer record will be fixed-sized.
Enable wrapping everywhere.

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).

For generic functions, we have to leave the builtins in OCALL form,
rather than transform to specific ops, since we don't know the exact
types involved. Allow export/import of builtins in OCALL form.
Added new export/import test mapimp.go.

Added new test typeparam/factimp.go and changed a bunch of other tests
to test exporting more generic functions and types.

This only moves functionality from one file into another.
Except for import adjustments there are no changes to the
code.
