[lworld] Integrated: 8256329: [lworld] C2 compilation fails with assert(!t->is_flat() && !t->is_not_flat()) failed: Should have been optimized out

In rare cases, the flat array check is not processed by IGVN and therefore not optimized out. The fix is to simply add it to the worklist during parsing.
