It's possible for the scheduler to try to preempt a goroutine running
on a thread created by C code just as the goroutine returns from Go code
to C code. If that happens, the goroutine will have a nil g,
which would normally cause us to enter the badsignal code.
The badsignal code will allocate an M, reset the signal handler,
and raise the signal. This is all wasted work for SIGURG,
as the default behavior is for the kernel to ignore the signal.
It also means that there is a period of time when preemption requests
are ignored, because the signal handler is reset to the default.
And, finally, it triggers a bug on 386 OpenBSD 6.2. So stop doing it.
No test because there is no real change in behavior (other than on OpenBSD),
the new code is just more efficient

Previously, the release notes broke up the sentences that modules
is now ready for production use and where to file issues for
migration problems into separate paragraphs. This made it look like
the migration paragraph was about upgrading to 1.14, not to modules,
and made the reading a bit confusing. Now the entire idea is in one
paragraph.

Currently, when mapping symbol's local index to global index, for
duplicated and overwriting/overwritten symbols, each appearance
of the symbol gets a global index, with one being the "primary",
and others "redirect" to it through the overwrite map. Basically,
the local-global index mapping is one to one, with overwrite/
dedup happening in global index level.
This has a few drawbacks:
- All symbol accesses effectively need to query the overwrite
map. This may hurt performance.
- For multi-level overwrites, (Y overwrites X, Z overwrites Y),
this can get quite complicated, and we have to follow the
redirection recursively.
- Failed to follow or to update the overwrite map leads to bugs.
In this CL, we change the index mapping mechanism so that each
symbol get a unique global index. Multiple appearances of the
same symbol get the same index. Now the local-global index
mapping is N to one. Overwrite/dedup happens directly in the
local-global mapping.
We keep both mapping directions in arrays. Each object carries
an array for its local-global mapping. The loader carries an
array mapping global index to the "primary" local index, which is
the one we should load from. This way, we can get rid of the
overwrite map, and index conversions are simply array accesses.
TODO: we still make reservation of the index space upfront, and
leave holes for dup symbols. Maybe get rid of the reservation and
holes.

Currently, the symbol updater uses a pointer pointing to the
loader's payloads array. If the payloads slice grows (and moves),
the pointer may become stale and no longer point to the symbol's
actual payload. Specifically, consider
sb, sym := l.MakeSymbolUpdater(...)
// add a bunch of external symbols, which grows payload slice
sb.SetType(t)
l.SymType(sym) // may not return t
sb.SetType on line 3 may not have the desired effect, as
sb.extSymPayload may no longer point to the right payload. As a
result, the type we get on line 4 may be not the one we set.
Fix this by making the payload's address permanent. Once it is
allocated it will never move.

Implementation changes in go/types for #6977 required that internal
LookupFieldOrMethod calls had access to the current *Checker. In
order to make quick progress, I added a *Checker receiver to the
function LookupFieldOrMethod (thus making it a method), and added
a new function LookupFieldOrMethod. The plan was always to rename
that function (Checker.LookupFieldOrMethod) such that it wouldn't
be exported; with the obvious name being Checker.lookupFieldOrMethod.
But that name was already in use which is why I postponed the rename.
Eventually I forgot to clean it up. This CL fixes that with the
following renames:
Checker.lookupFieldOrMethod => Checker.rawLookupFieldOrMethod
Checker.LookupFieldOrMethod => Checker.lookupFieldOrMethod

In CL 203820, we switched go/build to use the caller's working
directory for the main module (rather than srcDir), so that go/build
resolution now respects the requirements and replacements of the main
module. When the passed-in srcDir is empty, as of that CL we use "go
list" instead of falling back to in-process (GOPATH-mode) path lookup.
Unfortunately, that broke go/build.TestImportDirNotExist when
GO111MODULE=on: the test was looking for the specific error message
produced by the in-process lookup.
This change relaxes the test to accept the error message produced by
"go list" when srcDir is empty.
