golang.org/cl/174498 add ONAME case to isStaticCompositeLiteral, to
detect global variable as compile-time constant.
It does report wrong for struct field, e.g:
o := one{i: two{i: 42}.i}
field i in two{i: 42} was reported as static composite literal, while it
should not.
In general, adding ONAME case for isStaticCompositeLiteral is probably
wrong.
Fixes #31782
