It's clearer this way, because the `Interpolated` cases in `can_begin_const_arg` and `is_pat_range_end_start` are more permissive than the `Interpolated` cases in `can_begin_literal_maybe_minus`.
We currently use `can_begin_literal_maybe_minus` in a couple of places where only string literals are allowed. This commit introduces a more specific function, which makes things clearer. It doesn't change behaviour because the two functions affected (`is_unsafe_foreign_mod` and `check_keyword_case`) are always followed by a call to `parse_abi`, which checks again for a string literal.
