Like https://go.dev/cl/481376 did for encoding/gob,
but now for encoding/xml, which had very similar code.
One minor difference is that encoding/xml now needs a SetLen before the
call to Index, as otherwise we index just past the length.
Still, calling Grow and SetLen is easier to understand,
and avoids needing to make a new zero value.

CL 440035 added rewrite rules to simplify "costly" LEA
instructions, but the types in the rewrites were wrong and
the code would go bad if the wrong-typed register was spilled.
CL 482536 attempted to fix this by correcting the type in the
rewrite, but that "fix" broke something on windows-amd64-race.
Instead / for-now, remove the offending rewrite rules.

After performing a round trip on a connection, the connection is
usually returned to the idle connection pool. If the write of the
request did not complete successfully, the connection is not
returned.
It is possible for the response to be read before the write
goroutine has finished signalling that its write has completed.
To allow for this, the check to see if the write completed successfully
waits for 50ms for the write goroutine to report the result of the
write.
See comments in persistConn.wroteRequest for more details.
On a slow builder, it is possible for the write goroutine to take
longer than 50ms to report the status of its write, leading to test
flakiness when successive requests unexpectedly use different connections.
Set the timeout for waiting for the writer to an effectively
infinite duration in tests.

[This is a roll-forward of CL 479095, which was reverted due to a bad
interaction between inlining and escape analysis since fixed in CL 482355.]
Currently, when the inliner is determining if a function is
inlineable, it descends into the bodies of closures constructed by
that function. This has several unfortunate consequences:
- If the closure contains a disallowed operation (e.g., a defer), then
the outer function can't be inlined. It makes sense that the
*closure* can't be inlined in this case, but it doesn't make sense
to punish the function that constructs the closure.
- The hairiness of the closure counts against the inlining budget of
the outer function. Since we currently copy the closure body when
inlining the outer function, this makes sense from the perspective
of export data size and binary size, but ultimately doesn't make
much sense from the perspective of what should be inlineable.
- Since the inliner walks into every closure created by an outer
function in addition to starting a walk at every closure, this adds
an n^2 factor to inlinability analysis.
This CL simply drops this behavior.
In std, this makes 57 more functions inlinable, and disallows inlining
for 10 (due to the basic instability of our bottom-up inlining
approach), for an net increase of 47 inlinable functions (+0.6%).
This will help significantly with the performance of the functions to
be added for #56102, which have a somewhat complicated nesting of
closures with a performance-critical fast path.
The downside of this seems to be a potential increase in export data
and text size, but the practical impact of this seems to be
negligible:

When a closure is inlined, it may contain other hidden closures, which
the inliner will duplicate, rendering the original nested closures as
unreachable. Because they are unreachable, they don't get processed in
escape analysis, meaning that go/defer statements don't get rewritten,
which can then in turn trigger errors in walk. This patch looks for
nested hidden closures and marks them as dead, so that they can be
skipped later on in the compilation flow. NB: if during escape
analysis we rediscover a hidden closure (due to an explicit reference)
that was previously marked dead, revive it at that point.

Tests in package context cannot depend directly on package testing due to an import cycle.
We resolved this by having test functions in package context_test (x_test.go) forward to
test functions in package context (context_test.go). This is fragile, since it's easy
to add a test to context_test.go and forget to add the forwarding function, and tests
written in this way cannot easily use testing package features like t.Run for subtests.
It turns out that only four test functions actually use unexported members of package
context. This CL moves all except those four to x_test.go and makes them regular tests.
It also updates TestCause to use t.Run and t.Parallel to parallelize its test cases.
It also adds documentation indicating when tests should be added to each file.

zip.NewReader was recently improved to return ErrInsecurePath when
insecure entries are encountered.
This change adopts the same logic for the OpenReader interface as well.

The posix_fallocate syscall returns the result in r1 rather than in
errno:
> If successful, posix_fallocate() returns zero. It returns an error on failure, without
> setting errno.
Source: https://man.freebsd.org/cgi/man.cgi?query=posix_fallocate&sektion=2&n=1
Adjust the PosixFallocate wrappers on freebsd to account for that.
Also, CL 479715 used the same syscall wrapper for 386 and arm. However,
on arm the syscall argument order is different. The wrapper was
generated using mksyscall.go from the golang.org/x/sys/unix package,
adjusting the r1 check correspondingly.

Since the first client connection is explicitly closed before making
the second request, we cannot in general assume that the second
request uses a different port (it is equally valid to open the new
connection on the same port as the old one that was closed).

saferio.ReadData avoids unnecessary allocations because the buffer can be
preallocated with the right size (up to a limit) instead of having to resize
and copy it step by step.

exec.LookPath is equivalent to exec.findExecutable on linux.

Fix a regression caused by CL 463835. Unlike most platforms, solaris and
illumos don't use a libc_read_trampoline, so we need to skip one frame
less when using frame pointer unwinding in traceGoSysCall.
The solution is a bit hacky, so it might make sense to implement
gp.syscallbp if this causes more test failures in the future.
