Alessandro Di Federico f68b7866b3 Introduce BasicBlockID
This commit introduces `BasicBlockID` as the unique identifier for a
`efa::BasicBlock` into the CFG. A `BasicBlockID` is defined by a
`MetaAddress` plus an incremental integer. This enables us to have
multiple instances of the same block in a single function, which is
particularly useful when inlining multiple times the same function.

Apart from this, the commit also does the following:

* It drops representing `MetaAddress`es a `structs` in the IR. This created
  several issues related to ABI. We now represent them as strings.

* It defines more functions in `support.h`, instead of defining prototypes
  by hand in `CodeGenerator.cpp` and the like. Specifically, `unknownPC`
  and `raise_exception_helper`. We also introduce a C "constructor" for
  `PlainMetaAddress`.

* It significantly reduces the API of `GeneratedCodeBasicInfo`, which
  was supposed to be put on a diet since a long time.  Specifically,
  many jump target related methods have been moved to free functions in
  `IRHelpers.h`.  Also `GCBI::getSuccessors` has been pushed into its
  only user, `PruneRetSuccessors`, to prevent further usage of a
  deprecated API. In the future, it would be nice to drop it entirely.

* It introduces `efa::BasicBlock::InlinedFrom`.

* Introduce an enum to represent named argument indices for `newpc`.
  This enables us to more effectively manipulate its argument list.

* It improves the verification and error reporting for
  `efa::FunctionMetadata`.

* Update tests.

This commit is preliminary to another piece of work to improve the
generality of inlining beyond the simple "fake function" scenario, for
which the feature was originally conceived.
