667186f10f 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.

57a7a2d1cf Delete the really inefficient method: void remove(const Type* Typ); 
Speed up the symbol stripping code by avoiding a linear search of the
type table.

Get rid of removeEntry(type_iterator), since 'remove' is exactly the same
operation.

ffa96dc848 This fixes PR531, a crash when running the CBE on a bytecode file. 
The problem is that Function::renameLocalSymbols is iterating through
the symbol table planes, occasionally calling setName to rename a value
(which used to do a symbol table remove/insert pair).

The problem is that if there is only a single value in a particular type
plane that the remove will nuke the symbol table plane, and the insert
will create and insert a new one.  This hoses Function::renameLocalSymbols
because it has an iterator to the old plane, under the (very reasonable)
assumption that simply renaming a value won't cause the type plane to
disappear.

This patch fixes the bug by making the rename operation a single atomic
operation, which has a side effect of making the whole thing faster too. :)
