Nick Lewycky 54e62d71e0 Make Value::isDereferenceablePointer() handle unreachable code blocks. (This ...

returns false in the event the computation feeding into the pointer is
unreachable, which maybe ought to be true -- but this is at least consistent
with undef->isDereferenceablePointer().) Fixes PR11825!
