The documentation for TokenReader suggests that implementations of the
interface may return a token and io.EOF together, indicating that it is
the last token in the stream. This is similar to io.Reader. However, if
you wrap such a TokenReader in a Decoder it complained about the EOF.
A test was added to ensure this behavior on Decoder's.

On some platforms (currently ARM and ARM64), when calling into
VDSO we store the G to the gsignal stack, if there is one, so if
we receive a signal during VDSO we can find the G.
When an M exits, it frees the gsignal stack. But m.gsignal.stack
still points to that stack. When we call nanotime on this M, we
will write to the already freed gsignal stack, which is bad.
Prevent this by unlinking the freed stack from the M.
Should fix#35235.

In my experimentation, I had found that most non-SSAable expressions were

generally, as witnessed by issue #35213, which has a non-SSAable field reference
of a struct that is not converted to an autotmp. So, I fixed openDeferSave() to
handle non-SSAable nodes more generally, and make sure that these non-SSAable

effects).
