V4 IR: reduce runtime cost.

- Replace 2 QHash<BasicBlock *, ...> with QVector<...>, where the
  basic-block index is the index of the vector.
- Nearly all QHashes and QSets will have a minimal fill rate. So,
  initialize/reserve all of them with a reasonable minimal size to
  prevent re-allocations and re-hashing.
