Add `sizeof` hint in hover in the decompiler

Sometimes Hex-Rays decompiler inserts sizeof to the pseudocode, and sometimes you can’t force it to show its a different representation(as dec or hex), for example in memset intrinsic, and hint shows only int. This hurts readability and you have to inspect the argument of sizeof and calculate it yourself. Please add value hint to the hover, e.g. int, value = 42. Thanks!
