AlignedAtomicUint64 is 15 bytes and it takes 16 bytes in structures. On
32-bit systems, variables and structure fields is guaranteed to be
32-bit aligned and this means that we need only 12 bytes to find 8
contiguous bytes.

In this case, the task is already a subreaper, so setting this bit is a noop.

This change will allow us to remove the default link in a packetimpact test so
we can reduce indeterministic behaviors as required in https://fxbug.dev/78430.
This will also help with testing #1388.
Updates #578, #1388.

This CL introduces a 'checklinkname' analyzer, which provides rudimentary
type-checking that verifies that function signatures on the local and remote
sides of //go:linkname directives match expected values.
If the Go standard library changes the definitions of any of these function,
checklinkname will flag the change as a finding, providing an error informing
the gVisor team to adapt to the upstream changes. This allows us to eliminate
the majority of gVisor's forward-looking negative build tags, as we can catch
mismatches in testing [1].
The remaining forward-looking negative build tags are covering shared struct
definitions, which I hope to add to checklinkname in a future CL.
[1] Of course, semantics/requirements can change without the signature
changing, so we still must be careful, but this covers the common case.

Make hasSlot scan allocated slot, rather than the whole slice.
It is supposed to store physicalStart in usedSlot.

CR0.NE enables internal x87 floating point error reporting when set, else
enables PC style x87 error detection.
On AMD, the #MF exception isn't generated if CR0.NE isn't set.

Since cgroupfs.dir embedes cgroupfs.implStatFS, and dir.StatFS and
implStatFS.StatFS are identical, dir.StatFS is not needed.
