[dev.unified] cmd/compile/internal/noder: implicit conversion of call arguments
Function call arguments need to be implicitly converted to their
respective parameter types. This CL updates the Unified IR writer to
handle this case, at least for typical function calls. I'll handle
f(g()) calls is a subsequent CL.

This logic is a holdover from very early on when it wasn't as clear
how we would handle dictionary entries for derived types, particularly
ones that are emitted during desugaring.
However, the current plan is to explicitly wire runtime type info
through IR nodes, so we can drop this logic.
Notably, the "needed" bit is exposed to the go/types importers, so
removing it would break the x/tools importer. To minimize churn for
now, we can just leave the bools in place.

cmd/go/internal/modindex: disable indexing for modules outside GOROOT and the module cache
Since CL 410821 we were indexing these modules with a cache key based
on the mtimes of the files within the module. However, that seems to
be causing test failures (#53269 and maybe #53371).
In addition, indexing these modules caused a potentially-expensive
operation (re-indexing a whole module) whenever any individual file
within the module is changed, even if it isn't relevant to the
package(s) being loaded from that module. In some cases, that could
cause a significant performance regression for 'go' commands invoked
on a small subset of the packages in the module (such as running 'go
test' on a single changed package — a common case during development).
Instead, we now index only those modules found within the module cache
and within GOROOT.
In addition, we now check mtimes when indexing GOROOT modules if the
Go version begins with the string "devel ", which indicates a
non-released Go version that may include local file edits within GOROOT.

spec: clarify "slice of bytes" and "slice of runes" through examples
The spec section on conversions uses the terms "slice of bytes" and
"slice of runes". While not obviously clear, what is meant are slice
types whose element types are byte or rune types; specifically the
underlying types of the slices' element types must be byte or rune.
Some of this was evident from the examples, but not all of it. Made
this clearer by adding more examples illustrating various permitted
conversions.
Note that the 1.17 compiler did not accept the following conversions:
(where myByte, myRune, and myString have underlying types of byte,
rune, and string respectively) - it reported an internal error.
But it did accept the inverse conversions:
The 1.18 compiler made those conversions symmetric and they are now
permitted in both directions.
The extra examples reflect this reality.

go/types, types2: only set instance context if packages match
In CL 404885, we avoid infinite expansion of type instances by sharing a
context between the expanding type and new instances created during
expansion. This ensures that we do not create an infinite number of
identical but distinct instances in the presence of reference cycles.
This pins additional memory to the new instance, but no more
(approximately) than would be pinned by the original expanding instance.
However, we can do better: since type cycles are only possible within a
single package, we only need to share the local context if the two types
are in the same package. This reduces the scope of the shared local
context, and in particular can avoid pinning the package of the
expanding type to the package of the newly created instance.

runtime: use pidleget for faketime jump
In faketime mode, checkdead is responsible for jumping time forward to
the next timer expiration, and waking an M to handle the newly ready
timer.
Currently it pulls the exact P that owns the next timer off of the pidle
list. In theory this is efficient because that P is immediately eligible
to run the timer without stealing. Unfortunately it is also fraught with
peril because we are skipping all of the bookkeeping in pidleget:
* Skipped updates to timerpMask mean that our timers may not be eligible
for stealing, as they should be.
* Skipped updates to idlepMask mean that our runq may not be eligible
for stealing, as they should be.
* Skipped updates to sched.npidle may break tracking of spinning Ms,
potentially resulting in lost work.
* Finally, as of CL 410122, skipped updates to p.limiterEvent may affect
the GC limiter, or cause a fatal throw when another event occurs.
The last case has finally undercovered this issue since it quickly
results in a hard crash.
We could add all of these updates into checkdead, but it is much more
maintainable to keep this logic in one place and use pidleget here like
everywhere else in the runtime. This means we probably won't wake the
P owning the timer, meaning that the P will need to steal the timer,
which is less efficient, but faketime is not a performance-sensitive
build mode. Note that the M will automatically make itself a spinning M
to make it eligible to steal since it is the only one running.

cmd/go: set Root and target fields for packages in GOPATH
This change replicates the behavior filed in issue #37015 for packages
imported from the module index. That behavior is that packages that
happen to exist in a GOPATH src directory have p.Root and p.Target set
even when the packages are loaded from modules. This is likely
unintentional behavior because in module mode, packages shouldn't behave
differently depending on whether their directories exist in GOPATH. But
for uniformity, (and because two of our tests depend on this behavior),
this CL will implement this behavior. We can remove it from the module
index when we remove it from the go/build logic.
