Avoid migrating rodata symbols to functions if they are referenced by other data or rodata symbols.
Disallow data and rodata symbols from referencing jumptables.
BREAKING: Change the rodata migration algorithm.
- This allows for the algorithm to migrate unreferenced symbols that are between other symbols that do get migrated to the given function.
- The algorithm will now stop to migrate symbols as soon as it finds a symbol that should not be migrated to the current function (i.e. it should be migrated to other function, it is referenced by a data symbol, etc).
- This could be an abrupt change for projects that were relying on the old migration scheme, because some symbols may suddenly disappear, avoiding a correct build.
- This change should also reduce (and hopefully remove) the gaps generated between symbols during rodata migration.

Fix pointer tracking: fix garbage state of registers after function jumping outside of the current function.
