Bug 692342 - Remove the obviously superfluous uses of IsPointer(). r=mrbkap

Browse Source 
These are the easy cases, which all fall into one or more of the following categories:
* A check-and-throw, followed by a switch whose default case also throws
* A check of IsPointer() &&-ed with or tightly enclosing a check that implies IsPointer()
* A check of something clearly enforced by the XPIDL compiler
