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

Currently, there's no easy way to create `llvm::BitVector` with statically known bit pattern. Absence of convenient functionality like this may sway people to use `std::vector<bool>` instead.

This patch adds new `std::initializer_list`-based constructor that servers this purpose.
