Alessandro Di Federico dc48188f37 Introduce MetaAddress
`MetaAddress` replaces all the `uint64_t` used to represent a virtual
address. Its main features are:

* It has a non-zero representation of invalid addresses.
* It supports tags to represent code that has different interpretations but
  resides at the same address in memory (namely ARM vs Thumb).
* Arithmetic operations cannot overflow.
* It supports epochs, a way we intend to employ to handle self-modifying code
  (i.e., different code at the same address at different times).
* It supports "address spaces", which enable handling architectures with
  multiple address spaces.
* It fits in two 64-bit registers.
