[tree-ssa] Add missing GTY

With the appended patch, bootstrap come a bit further on the tree-ssa

It now stops with:
/usr/src/aj/cvs/gcc-tree-ssa-20020619-branch/gcc/tree-dfa.c: In function `dump_alias_info':
/usr/src/aj/cvs/gcc-tree-ssa-20020619-branch/gcc/tree-dfa.c:1922: warning: int format, different type arg (arg 4)

I'll fix this tomorrow but let's first solve this issue.

Ok to commit?
