Add a post-processing pass that updates the scores on callsites based
on how their results are used. This is similar to the "param feeds
unmodified into <XXX>" heuristics, but applies to returned results
instead: if we know that function F always returns a constant, and we
can see that the result from a given call feeds unmodified into an
if/switch, then decrease the score on the call to encourage inlining.

Add a new debug flag "-d=dumpinlcallsitescores" that dumps out a
summary of all callsites in the package being compiled with info on
inlining heuristics, for human consumption. Sample output lines:
Score Adjustment Status Callee CallerPos ScoreFlags
...
115 40 DEMOTED cmd/compile/internal/abi.(*ABIParamAssignment).Offset expand_calls.go:1679:14|6 panicPathAdj

Here "Score" is the final score calculated for the callsite,
"Adjustment" is the amount added to or subtracted from the original
hairyness estimate to form the score. "Status" shows whether anything
changed with the site -- did the adjustment bump it down just below
the threshold ("PROMOTED") or instead bump it above the threshold
("DEMOTED") or did nothing happen as a result of the heuristics
("---"); "Status" also shows whether PGO was involved. "Callee" is the
name of the function called, "CallerPos" is the position of the
callsite, and "ScoreFlags" is a digest of the specific properties we
used to make adjustments to callsite score via heuristics.

Introduce a new mode of execution for instrumenting packages that have
no test files. Instead of just skipping packages with no test files
(during "go test -cover" runs), the go command will invoke cmd/cover
on the package passing in an option in the config file indicating that
it should emit a coverage meta-data file directly for the package (if
the package has no functions, an empty file is emitted). Note that
this CL doesn't actually wire up this functionality in the Go command,
that will come in a later patch.

This patch changes the inliner to use callsite scores when deciding to
inline as opposed to looking only at callee cost/hairyness.
For this to work, we have to relax the inline budget cutoff as part of
CanInline to allow for the possibility that a given function might
start off with a cost of N where N > 80, but then be called from a
callsites whose score is less than 80. Once a given function F in
package P has been approved by CanInline (based on the relaxed budget)
it will then be emitted as part of the export data, meaning that other
packages importing P will need to also need to compute callsite scores
appropriately.
For a function F that calls function G, if G is marked as potentially
inlinable then the hairyness computation for F will use G's cost for
the call to G as opposed to the default call cost; for this to work
with the new scheme (given relaxed cost change described above) we
use G's cost only if it falls below inlineExtraCallCost, otherwise
just use inlineExtraCallCost.
Included in this patch are a bunch of skips and workarounds to
selected 'errorcheck' tests in the <GOROOT>/test directory to deal
with the additional "can inline" messages emitted when the new inliner
is turned on.

This suppresses the race reported in #62638.
I am not 100% certain how that race happens, but here is my theory.
The increment of reqNum happens before the server writes the response
headers, and the server necessarily writes the headers before the
client receives them. However, that write/read pair occurs through I/O
syscalls rather than Go synchronization primitives, so it doesn't
necessarily create a “happens before” relationship as defined by the
Go memory model: although we can establish a sequence of events, that
sequence is not visible to the race detector, nor to the compiler.
Fixes#62638.

When slog.Record.Add(args) is called, with enough args to cause the
Record.back []Attr to be created, it is being created 1 too small, which
results in it immediately being grown again by append before the function
exits (needless allocation and copying).
This is because it is created with a capacity equal to countAttrs(args),
but forgets that there is an additional attribute to be appended: a
(args is just the remaining unconsumed attributes).
This PR fixes that by adding 1 to the capacity to account for the `a` attribute.
Additionally, when Record.back already exists, it will most likely be at
max capacity already. Rather than append to it and risk having it grown
multiple times, or grow too large, this adds a slices.Grow call to set it
to the right capacity, similar to what is already done in the
Record.AddAttrs(attrs) function.

This CL clarifies the order of evaluation of the binary logical
operators, && and ||. The clarified semantics matches what cmd/compile
and x/tools/go/ssa already implement, and prohibit some optimizations
that are arguably allowed today but risk surprising users.
First, it specifies that the left operand is evaluated before the
right operand. This prohibits "(f() || true) && *p" from evaluating
"*p" before "f()".
Second, it specifies that binary logical operations are also ordered
lexically left-to-right with regard to function calls and receive
operations. This prohibits "h(*p || true || f(), g())" from evaluating
"*p" after "g()".
Finally, the "order of evaluation of [...] is not specified" wording
in the example is clarified to acknowledge that there are still some
other orderings that are implied lexically; e.g., x must be evaluated
and indexed before g(), and z now must be evaluated before h(). (Note:
Whether z is evaluated before or after f() remains unspecified, as
there's no lexical dependency.)

As far as I can tell, some flakiness is unavoidable in tests
that race a large client request write against a server's response
when the server doesn't read the full request.
It does not appear to be possible to simultaneously ensure that
well-behaved clients see EOF instead of ECONNRESET and also prevent
misbehaving clients from consuming arbitrary server resources.
(See RFC 7230 §6.6 for more detail.)
Since there doesn't appear to be a way to cleanly eliminate
this source of flakiness, we can instead work around it:
we can allow the test to adjust the hard-coded delay if it
sees a plausibly-related failure, so that the test can retry
with a longer delay.
As a nice side benefit, this also allows the tests to run more quickly
in the typical case: since the test will retry in case of spurious
failures, we can start with an aggressively short delay, and only back
off to a longer one if it is really needed on the specific machine
running the test.

Incorrect window resizing led to checksum error and invalid result.
To demonstrate the problem bigData must be a bit bigger, 3x is enough.
This change fixes window resizing, increases bigData size and decouples
TestLargeXXHash from bigData because it uses hardcoded hash value.

Now that types can self-report how many registers they need, it's much
easier to determine whether a parameter will fit into the available
registers: simply compare the number of registers needed against the
number of registers still available.
This also eliminates the need for the NumParamRegs cache.
Also, the new code in NumParamRegs is stricter in only allowing it to
be called on types that can actually be passed in registers, which
requires a test to be corrected for that. While here, change mkstruct
to a variadic function, so the call sites require less boilerplate.

For ELF targets, the code in the go linker that generates the
".shstrtab" section was using a loader symbol to accumulate the
contents of the section, then setting the section type to
sym.SELFROSECT. This resulted in a section whose offset indicated that
it fell into a loadable ELF segment, which is not how the .shstrtab is
supposed to work (it should be outside of all loadable segments,
similar to .strtab and .symtab). The peculiar .shstrtab caused
confusion in third party tools that operate on ELF files, notably
llvm-strip.
This patch rewrites the .shstrtab generation code to avoid using a
loader.Symbol and instead accumulate the contents of the section into
a regular byte slice, then emit the section's data in the same way
that .strtab is handled.
Fixes#62600.
