* Add a ValueMap<ValueOrSubclass*, T> type. ValueMap<Value*, T> is safe to useJeffrey Yasskin2009-10-224-0/+683
| | | | | | | | | | | | | even when keys get RAUWed and deleted during its lifetime. By default the keys act like WeakVHs, but users can pass a third template parameter to configure how updates work and whether to do anything beyond updating the map on each action. It's also possible to automatically acquire a lock around ValueMap updates triggered by RAUWs and deletes, to support the ExecutionEngine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84890 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | to break up CFG diamonds by banishing one of the blocks to the end of the function, which is bad for code density and branch size.
