e14c1d1f62 SIL, Optimizer: update and handle borrowed-from instructions
Compute, update and handle borrowed-from instruction in various utilities and passes.
Also, used borrowed-from to simplify `gatherBorrowIntroducers` and `gatherEnclosingValues`.
Replace those utilities by `Value.getBorrowIntroducers` and `Value.getEnclosingValues`, which return a lazily computed Sequence of borrowed/enclosing values.

d9826f6043 SimplifyBranch: don't leave an empty block after merging two basic blocks
Although empty blocks are cleaned up at the end of every Simplification pass, it's not legal SIL to have empty blocks and subsequent simplification passes may crash because of this.
