URL: https://github.com/llvm/llvm-project/commit/f0db054cf9a72f45cb7721f918c37305cd1d72b8 DIFF: https://github.com/llvm/llvm-project/commit/f0db054cf9a72f45cb7721f918c37305cd1d72b8.diff LOG: [lldb][ObjC][NFC] Use llvm::StringRef::consume_front(char) where possible (#173012) Now that the `llvm::StringRef::consume_front(char)` exists, lets use it to replace the `consumeChar` helper. Drive-by: * Also use the overload where we previously had to pass a single character as a string literal.
