Conflicts:
- src/cmd/compile/internal/walk/builtin.go
On dev.typeparams, CL 330194 changed OCHECKNIL to not require manual
SetTypecheck(1) anymore; while on master, CL 331070 got rid of the
OCHECKNIL altogether by moving the check into the runtime support
functions.
- src/internal/buildcfg/exp.go
On master, CL 331109 refactored the logic for parsing the
GOEXPERIMENT string, so that it could be more easily reused by
cmd/go; while on dev.typeparams, several CLs tweaked the regabi
experiment defaults.

Created functions to create GC shape type and names, based on a proposal
from Keith. Kept unsigned and signed integer types as different, since
they have different shift operations.
Included adding in alignment fields where padding is
required between fields, even though that seems like it will be fairly
uncommon to use.
Added some extra unusual struct typeparams (for testing the gcshape
names/types) in index.go test.

With this change, interfaces are "completed" on-demand, when needed,
and the respective information (set of all methods, type constraints)
is recorded in a new typeSet data structure.
As a consequence, interfaces don't need to be explicitly completed
anymore and (internal) uses of interfaces have become much simpler.
This change also introduces a new field Interface.complete to indicate
that all methods and embedded elements have been set up. This prevent
the computation and recording (!) of a partial type set for erroneous
programs (if we compute the partial type set and store it, subsequent
type set accesses use the wrong type set which may lead to follow-on
errors).

This CL changes typecheck and order to use Type.LinkString for
computing map keys instead of Type.NameString. As mentioned in the
LinkString docs (added by the previous CL), LinkString reliably maps
type identity to string equality as long as the LinkString calls all
happen within the same compilation unit (which they do here).
This eliminates the need for subsequent types.Identical checks.

The original names "ShortString" and "LongString" refer back to the
fmt verbs used to request their formatting styles. However, I always
get confused working with them, in particular because (1) the
"ShortString" description, which uses package-path qualification, is
actually generally longer than the "LongString" description, which
uses package-name qualification; and (2) the documentation mentions
how they're often used, but doesn't actually describe why they're safe
for those purposes.
This CL renames them to "LinkString" and "NameString", respectively,
based on their primary use cases. It also attempts to more completely
describe the strings they return and how they can be used correctly.

All other test files in the runtime/race package have race build
tag, except syso_test.go. The test is only relevant if the race
detector is supported. So apply the build tag.

TestCheck/issues.src was failing after running
rm -r $(go env GOROOT)/pkg/*/cmd
as the builders do when building binary releases.
For users who write programs that depend on go/types, it should be
reasonable for end users to run the tests for go/types as part of 'go
test all', and those tests should pass even if they installed Go from
a binary release.
The test case in issues.src was importing cmd/compile/internal/syntax
in order to check the reported package name.
I tried to fix the problem by having the test import from source
instead of from export data. Unfortunately, that changed the behavior
under test: the go/types.Package.Imports reports (and is documented to
report) a different set of imported packages when loading from source
as compared to when loading from export data.
For this particular test, after CL 313035 that difference resulted in
go/types treating the "syntax" name as ambiguous when importing from
source, because a transitive dependency on "regexp/syntax" is found
when loading from source but omitted when loading from export data.
The simple fix to make the package unambiguous again is to adapt the
test to import regexp/syntax directly. That not only makes the package
unambiguous with all importers, but also avoids depending on a
cmd-internal package that cannot be loaded from export data in binary
distributions of the Go toolchain.

TestStdlib was failing after running
rm -r $(go env GOROOT)/pkg/*/cmd
as the builders do when building binary releases.¹
For users who write programs that depend on go/types, it should be
reasonable to run the tests for go/types as part of 'go test all', and
those tests should pass even if they installed Go from a binary
release.
I had originally drafted this as a fallback to import from source only
if the affected packages can't be imported by the default export-data
importer. Unfortunately, I realized that we don't currently have a
builder that tests the actual release (#46900), so it is quite likely
that the fallback path would bit-rot and produce unexpected test
regressions.
So instead, we now unconditionally import from source in TestStdlib.
That makes the test substantially slower (~15s instead of ~5s on my
workstation), but with less risk of regression, and TestStdlib is
skipped in short mode already so short-mode test time is unaffected.
If we change the builders to test the actual release configuration, we
can consider restoring the faster path when export data is available.

While initially building out unified IR, I didn't have any indexing
scheme. Everything was written out in order. Consequently, if I wanted
to write A before B, I had to compute A before B.
One particular example of this is handling closure variables: the
reader needs the list of closure variables before it can start reading
the function body, so I had to write them out first, and so I had to
compute them first in a separate, dedicated pass.
However, that constraint went away a while ago. For example, it's now
possible to replace the two-pass closure variable capture with a
single pass. We just write out the function body earlier, but then
wait to write out its index.
I anticipate this approach will make it easier to implement
dictionaries: rather than needing a separate pass to correctly
recognize and handle all of the generics cases, we can just hook into
the existing logic.
