This is the start of the Go 1.20 development cycle, so update the
Version value accordingly. It represents the Go 1.x version that
will soon open up for development (and eventually become released).

c8d5ccf82e [dev.unified] go/internal/gcimporter: flatten imports
The current documentation for go/types.(*Packages).Imports requires
that the import graph be flattened when read from export data. I think
this is a documentation bug (incorrectly codifying the existing
behavior, rather than documenting it as a known bug), but until that's
decided, we can at least flatten imports ourselves.

Updates #54096.

ac0844ec27 [dev.unified] cmd/compile: move "has init" to private metadata
Currently, there's a "has init" bool in the public metadata section,
which is only needed by cmd/compile; but because it's in the public
metadata section, it's known to the go/types importers too. This CL
moves it instead to the new compiler-only private metadata section
added in the last CL for the inline bodies index.

The existing bool in the public metadata section is left in place, and
just always set to false, to avoid breaking the x/tools importer. The
next time we bump the export version number, we can remove the bool
properly. But no urgency just yet.

f995946094 [dev.unified] cmd/compile: implement simple inline body pruning heuristic
An important optimization in the existing export data format is the
pruning of unreachable inline bodies. That is, when re-exporting
transitively imported types, omitting the inline bodies for methods
that can't actually be needed due to importing that package.

The existing logic (implemented in typecheck/crawler.go) is fairly
sophisticated, but also relies on actually expanding inline bodies in
the process, which is undesirable. However, including all inline
bodies is also prohibitive for testing GOEXPERIMENT=unified against
very large Go code bases that impose size limits on build action
inputs.

As a short-term solution, this CL implements a simple heuristic for
GOEXPERIMENT=unified: include the inline bodies for all
locally-declared functions/methods, and for any imported
functions/methods that were inlined into this package.

3e97294663 runtime/cgo: use frame address to set g0 stack bound
For a cgo binary, at startup we set g0's stack bounds using the
address of a local variable (&size) in a C function x_cgo_init and
the stack size from pthread_attr_getstacksize. Normally, &size is
an address within the current stack frame. However, when  it is
compiled with ASAN, it may be instrumented to __asan_stack_malloc_0
and the address may not live in the current stack frame, causing
the stack bound to be set incorrectly, e.g. lo > hi.

Using __builtin_frame_address(0) to get the stack address instead.

that space padding is only available for day of the month.

Finally I add tests to show the behaviors in specific scenarios.

c5da4fb7ac cmd/compile: make jump table symbol local
When using plugins, if the plugin and the main executable both
have the same function, and if it uses jump table, currently the
jump table symbol have the same name so it will be deduplicated by
the dynamic linker. This causes a function in the plugin may (in
the middle of the function) jump to the function with the same name
in the main executable (or vice versa). But the function may be
compiled slightly differently, because the plugin needs to be PIC.
Jumping from the middle of one function to the other will not work.
Avoid this problem by marking the jump table symbol local to a DSO.

Fixes #53989.

Re-reviewing our repos now in 2022, the open-source lawyers are

To ease maintenance, remove AUTHORS and CONTRIBUTORS from all repos.

df38614bd7 test: use go tool from tree, not path
Some of our tests do exec.Command("go", "tool", "compile", ...) or
similar. That "go" is selected from PATH. When run.go is started
from the command line (but not from all.bash), the first "go" is whatever
happens to be first in the user's path (some random older version than
tip). We really want all these tests to use the "go" tool from the
source tree under test. Add GOROOT/bin to the front of the path to
ensure that the tools we use come from the source tree under test.
