Changes in directory llvm/lib/Target/CBackend:
Writer.cpp updated: 1.229 -> 1.230
---
Log message:
Make sure to remove all dead type names from the symbol table, not just
struct types. This fixes Regression/CodeGen/CBackend/2005-03-08-RecursiveTypeCrash.ll,
a crash on Java output that Alkis reported.
