These are straightforward variants of the existing Sprintf etc.,
but append the resulting bytes to a provided buffer rather than
returning a string.
Internally, there is potentially some allocation because the package
uses a pool of buffers to build its output. We make no attempt to
override that, so the result is first printed into the pool and
then copied to the output. Since it is a managed pool, asymptotically
there should be no extra allocation.

Currently, it's not possible to send informational responses such as
103 Early Hints or 102 Processing.
This patch allows calling WriteHeader() multiple times in order
to send informational responses before the final one.
If the status code is in the 1xx range, the current content of the header map
is also sent. Its content is not removed after the call to WriteHeader()
because the headers must also be included in the final response.
The Chrome and Fastly teams are starting a large-scale experiment to measure
the real-life impact of the 103 status code.
Using Early Hints is proposed as a (partial) alternative to Server Push,
which are going to be removed from Chrome:
https://groups.google.com/a/chromium.org/g/blink-dev/c/K3rYLvmQUBY/m/21anpFhxAQAJ

CL 395854 made inline pass to not inlining function with shape params,
but pass no shape arguments. This is intended to be the reverse case of
CL 361260.
However, CL 361260 is using wider condition than necessary. Though it
only needs to check against function parameters, it checks whether the
function type has no shape. It does not cause any issue, because
!fn.Type().HasShape() implies !fn.Type().Params().HasShape().
But for the reverse case, it's not true. Function may have shape type,
but has no shape arguments. Thus, we must tighten the condition to
explicitly check against the function parameters only.

Since CL 391014, cmd/compile now requires the -p flag to be set the
build system. This CL changes it to initialize LocalPkg.Path to the
provided path, rather than relying on writing out `"".` into object
files and expecting cmd/link to substitute them.
However, this actually involved a rather long tail of fixes. Many have
already been submitted, but a few notable ones that have to land
simultaneously with changing LocalPkg:
1. When compiling package runtime, there are really two "runtime"
packages: types.LocalPkg (the source package itself) and
ir.Pkgs.Runtime (the compiler's internal representation, for synthetic
references). Previously, these ended up creating separate link
symbols (`"".xxx` and `runtime.xxx`, respectively), but now they both
end up as `runtime.xxx`, which causes lsym collisions (notably
inittask and funcsyms).
2. test/codegen tests need to be updated to expect symbols to be named
`command-line-arguments.xxx` rather than `"".foo`.
3. The issue20014 test case is sensitive to the sort order of field
tracking symbols. In particular, the local package now sorts to its
natural place in the list, rather than to the front.
Thanks to David Chase for helping track down all of the fixes needed
for this CL.

The testCPUProfile helper function iterates until the profile contains
enough samples. However, in general very slow builders may need longer
to complete tests, and may have less-responsive schedulers (leading to
longer durations required to collect profiles with enough samples).
To compensate, slower builders generally run tests with longer timeouts.
Since this test helper already dynamically scales the profile duration
based on the collected samples, allow it to continue to retry and
rescale until it would exceed the test's deadline.

When compiling package runtime, cmd/compile logically has two copies
of package runtime: the actual source files being compiled, and the
internal description used for emitting compiler-generated calls.
Notably, CL 393715 will cause the compiler's write barrier validation
to start recognizing that compiler-generated calls are actually calls
to the corresponding functions from the source package. And today,
there are some code paths in nowritebarrierrec code paths that
actually end up generating code to call panicshift or panicdivide.
In preparation, this CL marks those functions as
//go:yeswritebarrierrec. We probably want to actually cleanup those
code paths to avoid these calls actually (e.g., explicitly convert
shift count expressions to an unsigned integer type). But for now,
this at least unblocks CL 393715 while preserving the status quo.

CL 395854 made inline pass to not inlining function with shape params,
but pass no shape arguments. But it does not consider the case where
function has shape params, but passing zero arguments. In this case, the
un-safe interface conversion that may be applied to a shape argument can
not happen, so it's safe to inline the function.
Fixes#52907

This is the same fix as CL 36126, but for the reverse case, function
with shape params but passed no shape arg. The same conversion problem
may occur in this case, see details explanation there.

Currently the GC CPU limiter doesn't account for idle application time
at all. This means that the GC could start thrashing, for example if the
live heap exceeds the max heap set by the memory limit, but the limiter
will fail to kick in when there's a lot of available idle time. User
goroutines will still be assisting at a really high rate because of
assist pacing rules, but the GC CPU limiter will fail to kick in because
the actual fraction of GC CPU time will be low if there's a lot of
otherwise idle time (for example, on an overprovisioned system).
Luckily, that idle time is usually eaten up entirely by idle mark
workers, at least during the GC cycle. And in these cases where we're
GCing continuously, that's all of our idle time. So we can take idle
mark work time and subtract it from the mutator time accumulated in the
GC CPU limiter, and that will give us a more accurate picture of how
much CPU is being spent by user goroutines on GC. This will allow the GC
CPU limiter to kick in, and reduce the impact of the thrashing.
There is a corner case here if the idle mark workers are disabled, for
example for the periodic GC, but in the case of the periodic GC, I don't
think it's possible for us to be thrashing at all, so it doesn't really
matter.
Fixes#52890.

Now that Ntype is gone, we no longer require separate sym and nod
fields for Type. It's now always the case that t.sym == t.nod.Sym(),
or that t.sym and t.nod are both nil.
While here, rename nod to obj, to better reflect that in fact it's
always an object (i.e., *ir.Name), not merely a type literal (which no
longer exists in package ir).

NewBasic and NewNamed take an Object (i.e., *ir.Name), so that callers
don't need to call SetNod. This CL changes NewTypeParam to follow the
same convention. Following up on recent Ntype removal, this allows
getting rid of Type.SetNod entirely.
While here, Type.SetSym is unused too.

Historically, the compiler used to use a name node to represent "nil".
Now, "nil" is represented by NilExpr, so it's not necessary to associate
a Sym with it anymore.

The indexed export data format encodes the local package's path as "",
because that's historically how we've represented it within
cmd/compile. The format also requires the local package to be first in
the exported list of packages, and was implicitly relying on ""
sorting before other, non-empty package paths.
We can't change the format without breaking existing importers (e.g.,
go/internal/gcimporter), but we can at least remove the dependency on
LocalPkg.Path being "".
