-// the function for a pointer to a basic block. This also means that basic-blocks cannot be removed
-// or renumbered.
-//
-// Note that currently there is one exception: after optimization and block scheduling, the
-// method setScheduledBlocks can be called once, to register a newly ordered list. For debugging
-// purposes, these blocks are not immediately renumbered, so renumberBasicBlocks should be called
-// immediately after changing the order. That will restore the property of having a corresponding
-// block-index and block-position-in-basicBlocks-vector.
-//
-// In order for optimization/transformation passes to skip uninteresting basic blocks that will be
-// removed, the block can be marked as such. After doing so, any access will result in a failing
