implement ARM array cookies.  Also fix a few unfortunate bugs:
  - throwing dtors in deletes prevented the allocation from being deleted
  - adding the cookie to the new[] size was not being considered for
    overflow (and, more seriously, was screwing up the earlier checks)
  - deleting an array via a pointer to array of class type was not
    causing any destructors to be run and was passing the unadjusted
    pointer to the deallocator
  - lots of address-space problems, in case anyone wants to support
    free store in a variant address space :)

Added support for register allocators to record which intervals are spill intervals, and where the uses and defs of the original intervals were in the original code.

Spill intervals can be hidden using the "-rmf-intervals=virt-nospills*" option.

I'm sure it is harmless.  Original commit message:
If PrototypeValue is erased in the middle of using the SSAUpdator
then the SSAUpdator may access freed memory.  Instead, simply pass
in the type and name explicitly, which is all that was used anyway.

function statics, file globals and static variables) that a frame contains. 
The StackFrame objects can give out ValueObjects instances for
each variable which allows us to track when a variable changes and doesn't
depend on variable names when getting value objects.

StackFrame::GetVariableList now takes a boolean to indicate if we want to
get the frame compile unit globals and static variables.

The value objects in the stack frames can now correctly track when they have
been modified. There are a few more tweaks needed to complete this work. The
biggest issue is when stepping creates partial stacks (just frame zero usually)
and causes previous stack frames not to match up with the current stack frames
because the previous frames only has frame zero. We don't really want to 
require that all previous frames be complete since stepping often must check
stack frames to complete their jobs. I will fix this issue tomorrow.

For GRExprEngine::EvalBind() (and called visitors), unifiy StoreE and AssignE.  Now StoreE (const Stmt*) represents the expression where the store took place, which is the assignment expression if it takes place in an assignment.  This removes some conceptual dissidence as well as removes an extra parameter from the Checker::PreVisitBind() visitor.  It also improves ranges and source location information in analyzer diagnostics.
