Normally, when fuzzing identifies a failure it saves the failing input
to the package's testdata directory. However, the testdata directory
for packages outside the main module is normally not writable — and
when it is, writing to a testdata directory inside the module cache
would corrupt the checksum for that module (and permanently alter the
behavior of that version of the module globally).
In the future we could consider a flag to allow failures to be saved
to an alternate location, or perhaps in the build cache; or, we could
suppress writes entirely and rely on the user to identify and copy the
failing input from the test log. However, it's a bit late in the cycle
for that big a design decision right now. For Go 1.18, we will just
enforce that the package to be fuzzed resides in the main module,
which is typically a writable VCS checkout.

We had been repeating conditions for specific platforms and
architectures to gate fuzzing tests, but the more of those tests we
add the more we will have to update if the set of supported platforms
and archictures expands over time.
We also ought to provide a friendlier error message when
'go test -fuzz' is used on non-supported platforms.
This change adds predicates in cmd/internal/sys, which already
contains similar predicates for related functionality (such as the
race detector), and uses those predicates in 'go test' and TestScript.

The net/http package has a documented contract that if DialContext, DialDLSContext, Dial or DialTLS are specified in an instance of Transport, that they will be used to set up the connection. If they are not specified, then a reasonable fallback is made (e.g. using the net package).
This is ordinarily true, except for when compiling for the js/wasm target, where the browser's Fetch API is preferred in all cases (except for when it is undefined/unavailable) and therefore the dial functions are all ignored. As a result, the http.Transport implementation under js/wasm doesn't meet that contract.
This PR updates the RoundTrip behaviour of http.Transport so that if DialContext, DialTLSContext, Dial or DialTLS are specified, they are used as expected. The Fetch API will be used as a fallback if they are not specified.

Now that we allow eliding 'interface' from constraint types, we need to
be a bit more careful about not consuming a '[' when parsing the next
expression after "type T [". We want to check if the next expression is
an identifier not followed by ']', in which case we're in a generic
type, but need to avoid parsing index or slice expressions. Such
expressions aren't valid array lengths because these expressions are
never constant, so when encountering a following '[' we can instead
assume that this is a type parameter field with array or slice type
constraint.

Previously, Go has assumed VCS checkouts are indicated by a dot-file

normally true for Fossil, but has worked so far since Go downloads
repositories into a ".fossil" file before opening (checking out).
Using the incorrect path prevents Go identifying Fossil checkouts and

Currently, for stack traces (e.g. at panic or when runtime.Stack
is called), we print argument values from the stack. With register
ABI, we may never store the argument to stack therefore the
argument value on stack may be meaningless. This causes confusion.
This CL makes the compiler keep trace of which argument stack
slots are meaningful. If it is meaningful, it will be printed in
stack traces as before. If it may not be meaningful, it will be
printed as the stack value with a question mark ("?"). In general,
the value could be meaningful on some code paths but not others
depending on the execution, and the compiler couldn't know
statically, so we still print the stack value, instead of not
printing it at all. Also note that if the argument variable is
updated in the function body the printed value may be stale (like
before register ABI) but still considered meaningful.
Arguments passed on stack are always meaningful therefore always
printed without a question mark. Results are never printed, as
before.
(Due to a bug in the compiler we sometimes don't spill args into
their dedicated spill slots (as we should), causing it having
fewer meaningful values than it should be.)
This increases binary sizes a bit:

Rename singleUnder to structure. The structure function returns
the "type structure" of a type, either its underlying type for

Change constraint type inference to use the structure type for
inference, unless the structure type is the underlying type of
a single defined type, in which case it uses the latter. This

easy to relax if need be). In some places (function calls through a

a more general behavior, matching other primary expressions or built-

The behavior of is/underIs was murky with the presence of a top type term
(corresponding to a type set that is not constrained by any types, yet the
function argument f of is/underIs was called with that term).
Change is/underIs to call f explicitly for existing specific type terms,
otherwise return the result of f(nil). Review all uses of is/underIs and
variants.
This makes the conversion code slightly more complicated because we need
to explicitly exclude type parameters without specific types; but the
code is clearer now.

Previously, the worker would attempt to deflake
an input that was reported to have caused new
coverage. The chances of a flake causing new
coverage seem pretty low to me, and even if it
was a flake that caused it, adding that input to
the cache doesn't seem like a bad thing. The
input is already going to be deflaked during
minimization anyway. If by some off-chance the
code is causing a lot of flaky coverage
increases, and the user doesn't want minimization
to occur, then setting -fuzzminimizetime=1x will
deflake in the way they want without minimizing.
This can be documented as needed.
This fixes a bug where the mem.header().count
could have been one too large if an unrecoverable
crash occured while deflaking an input that
caused code coverage.

cmd/go is not subject to all the same restrictions as most of cmd.
In particular it need not be buildable with the bootstrap toolchain.
So it is better to keep as little code shared between cmd/go and
cmd/compile, cmd/link, cmd/cgo as possible.
cmd/internal/str started as cmd/go/internal/str but was moved
to cmd/internal in order to make use of the quoted string code.
Move that code to cmd/internal/quoted and then move the rest of
cmd/internal/str back to cmd/go/internal/str.
