Log Message:
lint: fix handling of unnamed struct/union members

The support for unnamed struct/union members that was added in decl.c
1.60 from 2015-10-13 was simple but wrong. It didn't cover initializers
of these structures and computed wrong sizes for structures containing
anonymous unions. At that time, the handling of initializers was broken
as well, it was fixed 6 years later in init.c 1.229 from 2021-12-22.

Real-life examples for code that lint couldn't handle are:

        * external/bsd/jemalloc/dist/src/jemalloc.c
        * external/mit/xorg/lib/dri.old/Makefile
