Hi Zhongxing,
Can you tell me what your motivation was for implementing 'classof'
for AnonTypedRegion in this way? This will return true if the
MemRegion is a VarRegion or a FieldRegion, but not if it is an
instance of AnonTypedRegion (!). AnonTypedRegion is just meant to be
some lightweight layering on top of an existing region where we want
to add some typing information to a set of bytes.
