Description Mark Lam 2015-06-01 13:25:09 PDT

We currently track exceptions as 2 values in the VM: m_exception (the thrown JSValue) and m_exceptionStack (a capture of the stack trace at the time of throw).  This increases the complexity of having to keep the 2 values in sync every time we throw, clear, stash away, and restore exceptions.  We should introduce an Exception object to better encapsulate all the state pertaining to an exception throwing event.

After reviewing the needed changes, there's not enough difference between the patch for this bug and the fix for bug 145525 (which this bug is intended to build towards).  So, I'll just roll this bug into 145525 and implement the fix there.
