* Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficientlyChris Lattner2003-12-311-5/+21
| | | | | | | | | | | turn a memory address back into the LLVM global object that starts at that address. Note that this won't cause any additional datastructures to be built for clients of the EE that don't need this information. Also modified some code to not access the GlobalAddress map directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10674 91177308-0d34-0410-b5e6-96231b3b80d8

Move support for getting the value of a ConstantExpr into getConstantExprValue(), and add support for the rest of the different kinds of ConstantExprs. (I don't think I like ConstantExprs!) This requires separate procedures executeShlInst() and executeShrInst(). Reduce the number of references to TheEE. Get rid of an old comment mentioning annotations. Fix exitCalled(), which was crashing the Interpreter.
