This test used to run with a separate goroutine for timeout behavior,
presumably because it was difficult to set an appropriate timeout.
Now that the test is in cmd instead of misc, we can use
internal/testenv.Command, which makes adding the test timeout much
simpler and eliminates the need for the explicit goroutine.
For #61846.

Previously, os.Stat only followed IO_REPARSE_TAG_SYMLINK
and IO_REPARSE_TAG_MOUNT_POINT reparse points.
This CL generalize the logic to detect which reparse points to follow
by using the reparse tag value to determine whether the reparse point
refers to another named entity, as documented in
https://learn.microsoft.com/en-us/windows/win32/fileio/reparse-point-tags.
The new behavior adds implicit support for correctly stat-ing reparse
points other than mount points and symlinks, e.g.,
IO_REPARSE_TAG_WCI_LINK and IO_REPARSE_TAG_IIS_CACHE.

Historically, the Transport has silently truncated invalid
Host headers at the first '/' or ' ' character. CL 506996 changed
this behavior to reject invalid Host headers entirely.
Unfortunately, Docker appears to rely on the previous behavior.
When sending a HTTP/1 request with an invalid Host, send an empty
Host header. This is safer than truncation: If you care about the
Host, then you should get the one you set; if you don't care,
then an empty Host should be fine.
Continue to fully validate Host headers sent to a proxy,
since proxies generally can't productively forward requests
without a Host.

Now that pcvalue keeps its cache on the M, we can drop all of the
stack-allocated pcvalueCaches and stop carefully passing them around
between lots of operations. This significantly simplifies a fair
amount of code and makes several structures smaller.
This series of changes has no statistically significant effect on any
runtime Stack benchmarks.
I also experimented with making the cache larger, now that the impact
is limited to the M struct, but wasn't able to measure any
improvements.

Currently, the pcvalue cache is stack allocated for each operation
that needs to look up a lot of pcvalues. It's not always clear where
to put it, a lot of the time we just pass a nil cache, it doesn't get
reused across operations, and we put a surprising amount of effort
into threading these caches around.
This CL moves it to the M, where it can be long-lived and used by all
pcvalue lookups, and we don't have to carefully thread it across
operations.

This CL optimizes open-coded defers in two ways:
1. It modifies local variable sorting to place all open-coded defer
closure slots in order, so that rather than requiring the metadata to
contain each offset individually, we just need a single offset to the
first slot.
2. Because the slots are in ascending order and can be directly
indexed, we can get rid of the count of how many defers are in the
frame. Instead, we just find the top set bit in the active defers
bitmask, and load the corresponding closure.

Rather than testing for architectures that use libc-based system calls,
test that it is not the single architecture that Go is still using direct
system calls. This reduces the number of changes needed for new openbsd
ports.

The type machVMRegionBasicInfoData is generated from C type
vm_region_basic_info_data_64_t, which is a packed struct with a
64-bit field at offset 20. We cannot use uint64 as the field type
in the Go struct, as that will be aligned at offset 24, which does
not match the C struct. Change back to [8]byte (which is what the
cgo command generates), but keep the name Offset.
