Resolving within-procedure indirect calls

[l-kent]

Indirect calls can also be to other blocks in a procedure, not just to other procedures. We currently cannot resolve these. In these cases, the register called in the indirect call points to another block, not another procedure.

The test cases that include this behaviour are \test\correct\switch2\clang and \test\correct\jumptable3\clang (only the GTIRB versions, BAP just does not lift these structures properly at all unfortunately).
