LLVM Programmer’s Manual strongly discourages the use of `std::vector<bool>` and suggests `llvm::BitVector` as a possible replacement.

Currently, some users of `std::vector<bool>` cannot switch to `llvm::BitVector` because it doesn't support range-based for loops. (Note: `BitVector` currently only provides iterator over set bits.)

To enable easy transition of `std::vector<bool>` users, this patch implements `llvm::BitVector::begin()` and `llvm::BitVector::end()`.

Depends on D117115 <https://reviews.llvm.org/D117115>.
