This change introduces some duplication but ensures an important property of `tuple_tree_generate`d: data structures: all the leaves are scalars. Previously, yield::Function was using efa::BasicBlock, making things more difficult under certain conditions. Specifically, we can rely on the fact that, when generating a visit to the TupleTree, we know everything about all non-scalars.

This flag is set to `false` for basic blocks that are never directly
|
|
pointed to, i.e. blocks that are only ever entered from the previous
|
|
instructions and such.
|
|
This lets us dynamically decide whether we want to show labels like this
|

or not.

This flag is set if the last instruction of the block is in a delay slot
|
|
and is executed at the same time as the instruction preceding it.
|
|
\note: This is always equal to `false` on architectures that do not
|
|
support delay slots.
