cmd/gc: don't walk static nodes generated by anylit.
During anylit run, nodes such as SLICEARR(statictmp, [:])
may be generated and are expected to be found unchanged by
gen_as_init.
In some walks (in particular walkselect), the statement
may be walked again and lowered to its usual form, leading to a
crash.
Fixes issue 8017.
Fixes issue 8024.
Fixes issue 8058.
