  Log Message:
  -----------
  [Clang] Do not warn for serialized builtin or command-line definitions (#137306)

When using `-dD` to generate a preprocessed output, the `#define`
directives
are preserved. This includes built-in and command-line definitions.

Before, clang would warn for reserved identifiers for serialized
built-in
and command-line definitions.
This patch adds an exception to these cases.
