Jay Conrod 97df3ba792 [dev.fuzz] internal/fuzz: refactor in preparation for GOFUZZCACHE
Several small changes, most related to GOFUZZCACHE.

* Use separate channels to send crashers and interesting values to the
  coordinator.
* Add a new type, crasherEntry, which is a corpusEntry with an
  error message.
* Workers now send fatal errors to the coordinator via errC instead of
  returning or closing doneC.
* In CoordinateFuzzing, defer code that closes doneC and waits for
  workers to stop. This is the only place where doneC is closed.
* In workerServer and workerClient, always pass input values through
  shared memory instead of RPC messages or arguments to avoid
  confusion.
* Rename sharedMem.value to valueRef and add valueCopy to make it
  clearer whether a reference or copy is needed.
* mutate now operates on shared memory directly.
* mutate will not panic on empty input.

Cuong Manh Le 0a02371b05 cmd/compile: set correct type for OpIData
Since CL 270057, there're many attempts to fix the expand_calls pass
with interface{}-typed. But all of them did not fix the root cause. The
main issue is during SSA conversion in gc/ssa.go, for empty interface
case, we make its type as n.Type, instead of BytePtr.

To fix these, we can just use BytePtr for now, since when itab fields
are treated as scalar.

No significal changes on compiler speed, size.

The cmd module was updated as well, but go mod tidy undoes the change
because the x/net module doesn't contribute any packages to cmd module.

Than McIntosh 56b783ad94 cmd/go, cmd/asm: pass -linkshared to assembler for shared linkage builds
When the -linkshared build mode is in effect, the Go command passes
the "-linkshared" command line option to the compiler so as to insure
special handling for things like builtin functions (which may appear
in a shared library and not the main executable). This patch extends
this behavior to the assembler, since the assembler may also wind up
referencing builtins when emitting a stack-split prolog.

Fixes #43107.

Also remove the testenv.HasSrc-like check for Go source. The doc.go

Rob Findley 01b76d5fbc go/types: correct error position for inherited const init expressions
This is a port of CL 275517 from the dev.typeparams branch, to fix the
positioning of error messages for invalid const init expressions that
are inherited.

Differences from CL 275517:
 + The inherited flag is added to the constDecl intermediate
   representation.
 + The errpos override is made a positioner, the internal interface
   used by go/types to capture error position and span. For const decls
   errpos is just set to a singular point, but using positioner is
   correct and causes span start and end positions to also be
   overridden.
 + Test cases are updated to assert on just 'overflows', as the go/types
   error message is, for example, "cannot use 255 + iota (untyped int
   constant 256) as byte value in constant declaration (overflows)".
   This is more verbose than the compiler's "constant 256 overflows
   byte", but changing that is out of scope.

Jason A. Donenfeld be9379f8a8 syscall: correct CertOpenStore to expect a 0 return value on failure
According to [1], this function returns NULL when it errors, rather than
INVALID_HANDLE_VALUE, which other Win32 functions return. This was
pointed out in CL 273446 for the x/sys package, and this patch here
cleans it up for the syscall package and updates the vendored x/sys
package using the usual `go get/go mod vendor` dance. The function is
currently in use by crypto/x509/root_windows.go, which calls
CertOpenStore(CERT_STORE_PROV_MEMORY), which I assume can fail under OOM
or other weird conditions. Quick reversing indicates that [1] is
correct, as there's a `xor eax, eax` in the error paths of the function
just before jumping to the epilogue.

Jay Conrod 35f3b7053a [dev.fuzz] internal/fuzz: add mutex to workerClient
This prevents workerClient.Close from closing fuzzIn while
workerClient.fuzz is writing to it concurrently. It also prevents
multiple callers from writing to fuzzIn concurrently, though there's
nothing that does that yet.

This should prevent most "broken pipe" errors, though they may still
be possible if worker.stop is called and it needs to kill the process
due to a timeout. In the future, we should detect and ignore those
errors, but for now, they're useful for debugging.

Also, improve documentation on workerClient and workerServer.

Deletes the exported testing.Fuzz function

which were previously removed, this will
likely be too complex to support.

Moves the deferred Exit in f.Fuzz higher up
the function so it is always run.
