¶llvm::BasicBlock* SplitBlock(
    llvm::BasicBlock* Old,
    llvm::Instruction* SplitPt,

Description

Split the specified block at the specified instruction. If \p Before is true, splitBlockBefore handles the block splitting. Otherwise, execution proceeds as described below. Everything before \p SplitPt stays in \p Old and everything starting with \p SplitPt moves to a new block. The two blocks are joined by an unconditional branch. The new block with name \p BBName is returned. FIXME: deprecated, switch to the DomTreeUpdater-based one.
