Don't inline a function fn that has no shape parameters, but is passed
at least one shape arg. This means we must be inlining a non-generic
function fn that was passed into a generic function, and can be called
with a shape arg because it matches an appropriate type parameter. But
fn may include an interface conversion (that may be applied to a shape
arg) that was not apparent when we first created the instantiation of
the generic function. We can't handle this if we actually do the
inlining, since we want to know all interface conversions immediately
after stenciling. So, we avoid inlining in this case.

Update cmd/doc and go/doc for the generics, by adding handling for type
parameters and the new embedded interface elements.
Specifically:
- Format type parameters when summarizing type and function nodes.
- Find the origin type name for instantiation expressions, so that
methods are associated with generic type declarations.
- Generalize the handling of embedding 'error' in interfaces to
arbitrary predeclared types.
- Keep embedded type literals.
- Update filtering to descend into embedded type literals.
Also add "any" to the list of predeclared types.

The x/sys/windows package currently uses go:linkname for other facilities
inside of runtime that are not suitable to be exposed as a public API
due to their dangers but are still necessary for manipulating any
low-level plumbing that the runtime controls.
Logging, via the built-in println and panic handler, is one such
low-level plumbing feature. In this case, x/sys/windows/svc needs to be
able to redirect panics to the Windows event log. Because the event log
is a complicated interface, this requires a bit more fiddling than the
simple solution used on Android (baking it into runtime itself), and
because Windows services are very diverse, the event log might not even
always be a desirable destination.
This commit accomplishes this by exposing a function pointer called
"overrideWrite" that low-level runtime packages like x/sys/windows/svc
can use to redirect output logs toward the event log or otherwise.
It is not safe or acceptable to use as a generic mechanism, and for that
reason, we wouldn't want to expose this as a real stable API, similar to
the other instances of go:linkname in x/sys/windows. But for packages
that must interoperate with low-level Go runtime fundamentals, this is a
safety hatch for packages that are developed in tandem with the runtime.
x/sys/windows is one such package.

The test had been setting an arbitrary 200ms timeout to allow the
server's handler to set up before timing out. That is not only
potentially flaky on slow machines, but also typically much longer
than necessary. Replace the hard-coded timeout with a much shorter
initial timeout, and use exponential backoff to lengthen it if needed.
This allows the test to be run about 20x faster in the typical case,
which may make it easier to reproduce rare failure modes by running
with a higher -count flag.

These functions are exported for the compiler and are used after

This opens the door to moving them into the compiler eventually.
They may also be slightly more efficient.

and signal handlers installed by non-Go code. As such, stop using the X3 register so
that there are fewer issues interacting between Go and non-Go code.
While here remove the X4 (TP) name from the assembler such that any references must

Previously, opening a zip with (*Reader).Open could result in a panic if
the zip contained a file whose name was exclusively made up of slash
characters or ".." path elements.
Open could also panic if passed the empty string directly as an argument.
Now, any files in the zip whose name could not be made valid for
fs.FS.Open will be skipped, and no longer added to the fs.FS file list,
although they are still accessible through (*Reader).File.
Note that it was already the case that a file could be accessible from
(*Reader).Open with a name different from the one in (*Reader).File, as
the former is the cleaned name, while the latter is the original one.
Finally, made the actual panic site robust as a defense-in-depth measure.
