LE Manh Cuong 004fb5cb8d cmd/compile: fix isStaticCompositeLiteral reports wrong for struct field
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
