Similar to #3705, we actually have a mix of `Make` and `Create` in factory functions too, so this PR is normalizing on `Make`. It's intended to be consistent with the naming choice for Carbon factory functions. Note, MakeSyntheticBlock is the only one I feel a little weird about because llvm's own APIs use Create, and this is essentially wrapping LLVM calls. But the flipside is it also feels like a vague line to draw, when we also differ from LLVM coding style in other ways.
