The Read method on the Body returned from a net/http.Transport does
not wrap errors returned by the underlying io.Reader and returns a
bare io.ErrUnexpectedEOF if the body is shorter than the declared
Content-Length.
Since we can't feasibly add detail on the net/http side without
breaking established users, we must instead add detail on the caller
side. Since the net/http client uses url.Error for most of its own
errors, we use that same error type here.
I have not added a regression test for this change. (While it is
theoretically possible to set up a GOPROXY that returns incorrect
Content-Length headers, the change seems straightforward enough that
it isn't worth the complex test setup.)

Add cycle detection to hasVarType to avoid infinite recursions
caused by invalid cyclic types. This catches cases where the
validType check has not yet run or has checked differently
instantiated types.
As an alternative, validType could mark invalid *Named types
by setting their underlying types to Typ[Invalid]. That does
work but discards information which leads to undesired effects
with other errors. A better mechanism might be to explicitly
track in *Named if a type is invalid and why it is invalid,
and connect that with a general validity attribute on types.
That's a more invasive change we might consider down the road.

For map composite literals where the key type is a suitably constrained
type parameter, the existing key duplicate detection mechanism doesn't
work when the keys are numeric values of different types but equal value.
For instance, given
func _[P int64|float64]() {
_ = map[P]string{0: "foo", 0.0: "bar"}
}
the key values 0 and 0.0 have the same numeric value 0 but currently
are treated as different values int64(0) and float64(0.0). For any
valid instantiation of P, the keys will collide.
This CL changes the keyVal function to map numeric types to the
"smallest" numeric type in which a value can be represented. For
instance, float64(0.0) is mapped to int64(0). This ensures that
numerically equal values are always represented the same way so
that they can be detected as duplicates.

libFuzzer provides a special mode known as “value profiling” in which it
tracks the bit-wise progress made by the fuzzer in satisfying tracked
comparisons. Furthermore, libFuzzer uses the value of the return address
in its hooks to distinguish the progress for different comparisons.
The original implementation of the interception for integer comparisons
in Go simply called the libFuzzer hooks from a function written in Go
assembly. The libFuzzer hooks thus always see the same return address
(i.e., the address of the call instruction in the assembly snippet) and
thus can’t distinguish individual comparisons anymore. This drastically
reduces the usefulness of value profiling.
This is fixed by using an assembly trampoline that injects synthetic but
valid return addresses on the stack before calling the libFuzzer hook,
otherwise preserving the calling convention of the respective platform
(for starters, x86_64 Windows or Unix). These fake PCs are generated
deterministically based on the location of the compare instruction in
the IR representation.

IR string compares as well as calls to string comparison functions such
as `strings.EqualFold` are intercepted and the corresponding libFuzzer
callbacks are invoked with the corresponding arguments. As a result, the
compared strings will be added to libFuzzer’s table of recent compares,
which feeds future mutations performed by the fuzzer and thus allow it
to reach into branches guarded by string comparisons.
The list of methods to intercept is maintained in
`cmd/compile/internal/walk/expr.go` and can easily be extended to cover
more standard library functions in the future.

Currently, physical-page-aligned allocations for stacks (where the
physical page size is greater than the runtime page size) first
overallocates some memory, then frees the unaligned portions back to the
heap.
However, because allocating via h.pages.alloc causes scavenged bits to
get cleared, we need to account for that memory correctly in heapFree
and heapReleased. Currently that is not the case, leading to throws at
runtime.
Trying to get that accounting right is complicated, because information
about exactly which pages were scavenged needs to get plumbed up.
Instead, find the oversized region first, and then only allocate the
aligned part. This avoids any accounting issues.
However, this does come with some performance cost, because we don't
update searchAddr (which is safe, it just means the next allocation
potentially must look harder) and we skip the fast path that
h.pages.alloc has for simplicity.

By using libFuzzer’s 8-bit counters instead of extra counters, the
coverage instrumentation in libFuzzer mode is improved in three ways:
1- 8-bit counters are supported on all platforms, including macOS and
Windows, with all relevant versions of libFuzzer, whereas extra
counters are a Linux-only feature that only recently received
support on Windows.
2- Newly covered blocks are now properly reported as new coverage by
libFuzzer, not only as new features.
3- The NeverZero strategy is used to ensure that coverage counters
never become 0 again after having been positive once. This resolves
issues encountered when fuzzing loops with iteration counts that
are multiples of 256 (e.g., larger powers of two).

This benchmark is added to test improvements in memclr_amd64.
As it is stated in Intel Optimization Manual 15.16.3.3, AVX2-implemented
memclr can produce a skewed result with the branch predictor being
trained by the large loop iteration count.
This benchmark generates sizes between some specified range. This should
help to measure how memclr works when branch predictors may be incorrectly
trained.

For a host test we build the test using "go test -c" and then run the
test binary. A test binary run in this way has no default timeout.
This CL gives it a timeout of 5 minutes, scaled for the target.
We can adjust the timeout if necessary.

In https://golang.org/cl/263542 we added BuildID to the Package struct
in the docs for "go list", correctly pointing out that it's only set
when -export is used.
Further down, the doc details the -export flag on its own.
It already mentioned the Export field, and we forgot to add a mention to
BuildID as well. Do that.
