[dev.typeparams] all: merge master (46fd547) into dev.typeparams

2021-08-12T19:43:12+00:00

Conflicts:

- src/go/types/check_test.go

  CL 324730 on dev.typeparams changed the directory paths in TestCheck,
  TestExamples, and TestFixedbugs and renamed checkFiles to testFiles;
  whereas CL 337529 on master added a new test case just above them and
  that used checkFiles.

[dev.typeparams] cmd/compile: change export version to 1.17 for testing

2021-08-11T19:48:50+00:00

This is a temporary change. We will revert this back before the 1.18
release. We make this change now to simplify testing, since a lot of
tools will break on the new export version.

Updates #47654.

[dev.typeparams] go/types: don't expose the TypeSet API for 1.18

2021-08-10T21:49:07+00:00

The TypeSet API is very new and probably not necessary to expose outside
of go/types, at least for 1.18. Users can check whether a type is
contained within a type set via Implements, and can access the
representation of the type set via the embedded Unions.

[dev.typeparams] cmd/compile: keep export format unchanged if no type params are exported

2021-08-10T19:48:58+00:00

Added new export tags 'G' and 'U' to export parameterized
functions/methods and parameterized types respectively. This has the
advantage that the Go 1.18 format remains backward-compatible with the
Go 1.17 format if no type parameters are exported.

Remove a stale comment from when the new types.Info API was guarded
behind the typeparams build constraint.

As with other go/types APIs, we should not expose the underlying
Named.targs slice.
