If this is a constant expression that can be converted to a constant of the given type, this method should return the corresponding llvm::Constant value and a flag denoting if it's valid for multi-target compilation for use as an initializer of a global variable. Otherwise it should return the llvm::constant value as NULL.

This is the main method for Expr implementations to implement. It should call methods in the FunctionEmitContext to emit LLVM IR instructions to the current basic block in order to generate an llvm::Value that represents the expression's value.
