44ed517c42 cmd/go/internal/load: make check for path in import error more robust
When producing an ImportPathError from ImportErrorf, we check to see
whether the error string contains the path for the error. The issue is
that we were checking for the exact path string when sometimes the
string is quoted when the error is constructed, and the escaping in the
quote may not match the path string. Check for both the path string, and
the quoted path string.

Fixes #68737

03e5d83ca7 cmd/internal/obj: minor refactor of wasmimport code
This CL does some minor refactoring of the code handling
wasmimport.
- Put the WasmImport aux reading and writing code together for
  symmetry.
- Define WasmFuncType, embedded in WasmImport. WasmFuncType could
  also be used (later) for wasmexport.
- Move code generation code to a separate function. The containing
  function is already pretty large.
- Simplify linker code a little bit. The loader convention is to
  return the 0 Sym for nonexistent symbol, instead of a separate
  boolean.

No change in generated code. Passes toolstash -cmp
(GOARCH=wasm GOOS=wasip1 go build -toolexec "toolstash -cmp" -a std cmd).

d465aee0b8 cmd/internal/testdir: fix failure when GOAMD64=v3 is specified in goenv file
Fixes #68548

Add GOENV=off, GOFLAGS= to the build of the stdlib, so that it matches
what runcmd does. This ensures that the runtime and the test are built
with the same flags. As opposed to before this CL, where flags were used
in the stdlib build but not the runcmd build.

(Part of the problem here is that cmd/internal/testdir/testdir_test.go
plays fast and loose with the build cache to make the tests run faster.
Maybe some of that fast-and-loose mechanism can be removed now that we
have a better build cache? I'm not sure.)

e8776e19b9 runtime: benchmark mutex handoffs
The speed of handing off a mutex to a waiting thread is sensitive to the
configuration of the spinning section of lock2. Measure that latency
directly, to complement our existing benchmarks of mutex throughput.

aac7106cb9 crypto/tls: fix testHandshake close flakes

FreeBSD seems affected, maybe other TCP stacks handle sending on a

RST over localhost.

e50913cefc runtime: avoid futile mark worker acquisition
During the GC mark phase, one of the first behaviors of findRunnable is
to check if it should execute a GC mark worker. Mark workers often run
for many milliseconds in a row, so programs that invoke the scheduler
more frequently will see that condition trigger only a tiny fraction of
the time.

Obtaining a mark worker from the gcBgMarkWorkerPool involves a CAS on a
single memory location that's shared across the process. When GOMAXPROCS
is large, the resulting contention can waste a significant amount of CPU
time. But a sufficiently large GOMAXPROCS also means there's no need for
fractional mark workers, making it easier to check ahead of time if we
need to run a worker.

Check, without committing to a particular worker, whether we would even
want to run one.

2caf638e2f runtime: don't use maps in js note implementation
notes are used in sensitive locations in the runtime, such as those with
write barriers forbidden. Maps aren't designed for this sort of internal
use.

Notably, newm -> notewakeup doesn't allow write barriers, but mapaccess1
-> panic contains write barriers. The js runtime only builds right now
because the map access is optimized to mapaccess1_fast64, which happens
to not have a panic call.

The initial swisstable map implementation doesn't have a fast64 variant.
While we could add one, it is a bad idea in general to use a map in such
a fragile location. Simplify the implementation by storing the metadata
directly in the note, and using a linked list for checkTimeouts.

For #54766.

6ac87aa5b3 runtime: measure speed of procyield and osyield
These are delay primitives for lock2. If a mutex isn't immediately
available, we can use procyield to tell the processor to wait for a
moment, or osyield to allow the OS to run a different process or thread
if one is waiting. We expect a processor-level yield to be faster than
an os-level yield, and for both of them to be fast relative to entering
a full sleep (via futexsleep or semasleep).

Each architecture has its own way of hinting to the processor that it's
in a spin-wait loop, so procyield presents an architecture-independent
interface for use in lock_futex.go and lock_sema.go.

Measure the (single-threaded) speed of these to confirm.

bd85a3b153 cmd/internal/obj/loong64: remove Class C_LEXT and C_SEXT
There is no need to check whether the symbol is empty, since we have already
checked it before. In addition, it is enough to use C_ADDR to represent memory
access, C_LEXT and C_SEXT are not needed.

38c427c9dc net: replace sort with slices for address and DNS record sorting
This change replaces the usage of the "sort" package with the "slices"
package for sorting IP addresses and DNS records. The new approach
simplifies the code and improves readability by leveraging the
slices.SortFunc and slices.SortStableFunc functions.

- Updated addrselect.go to use slices.SortStableFunc for sorting IP
  addresses based on RFC 6724.
- Refactored dnsclient.go to use slices.SortFunc for sorting SRV and MX
  records by priority and weight.

This change also reduces the dependency tree for the package by
removing the dependency on "sort" and its transitive dependencies,
resulting in a leaner build.
