[5/8] widl: dereference operator in expr work on any declared pointer

[Michael Karcher]

If we take MIDL 6.00.0366 as reference, the following method type is
legal:

	void frobnicate([size_is(x),in,out] int * bar1,
                        [size_is(*bar1),out] int * bar2,
                        [in] int x);

Without this patch, size_is(*bar1) would be rejected.
