Alessandro Di Federico d10178483d Introduce the new MetaAddress ...

Unlike the previous iteration of `MetaAddress`, which tried to stuff all
the parts of `MetaAddress` within the existing `PC` CSV, this
implementation adds a set of new CSVs (or marks some existing ones as) to
represent the four portions of the current PC's `MetaAddress`.

* Introduce `ProgramCounterHandler`: a class responsible to maintain the
  PC-related CSVs. This class is also used to manipulate the new
  dispatcher.
* `AdvancedValueInfo`: update for new MetaAddress.
* External jump handler: do not clobber registers.
  When introducing support for dynamic binaries, we didn't realize that
  in x86-64 we were clobbering `r11`. To avoid this, we have to jump to
  an address stored in memory. However, due to the new `MetaAddress`,
  obtaining a *jumpable* address from the PC-related CSVs might require
  some computations (and it does in ARM). Therefore, we introduce a new
  global variable, `jumpablepc`, whose only role is to contain the
  jumpable version of the program counter and then be the target of the
  memory-indirect jump instruction.
* Labels care only about absolute addresses.
* CSAA: mark call site, even if no accesses.
