A basic block is part of an SCFG.
It can be treated as a function in continuation passing style. A block consists of a sequence of phi nodes, which are "arguments" to the function, followed by a sequence of instructions. It ends with a Terminator, which is a Branch or Goto to another basic block in the same SCFG.
