For expressions that have values based on a symbol (e.g. regular symbol references, array indexing, etc.), this returns a pointer to that symbol.

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.

Returns the type of the value returned by GetLValueType(); this should be a pointer type of some sort (uniform or varying).

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.

This method should perform type checking of the expression and return a pointer to the resulting expression. If an error is encountered, NULL should be returned.
