* Generalize tail continues * Fix DecodeBasicBlock `Next` and `Branch` would be null, which is not the state expected by the branch instructions. They end up branching or falling into a block which is never populated by the `Translator`. This causes an assert to be fired when building the CFG. * Clean up Decode overloads * Do not synchronize when branching into exit block If we're branching into an exit block, that exit block will tail continue into another translation which already has a synchronization. * Remove A32 predicate tail continue If `block` is not an exit block then the `block.Next` must exist (as per the last instruction of `block`). * Throw if decoded 0 blocks Address gdkchan's feedback * Rebuild block list instead of setting to null Address gdkchan's feedback
