Fix PR 6844, a regression caused by the introduction of llvm_unreachable for the default
case in GRExprEngine::Visit (in r101129).  Instead, enumerate all Stmt cases and have
no 'default' case in the switch statement.  When we encounter a Stmt we don't handle,
we should explicitly add it to the switch statement.
