Mem Semantics

[shunshou]

Edit: Nevermind. I guess I was doing something silly. But I'd still like to know what isDebugMem, isInlineMem, and isVCDMem do...

Edit2: When isDebugMem is true, write to mem still errors out, b/c needWidth (for random output when read addr = write addr) can't figure out the memory width? I changed needWidth to dataIn.getWidth to make it work...
