tools/clang/codesearch: support building with -Wchanges-meaning

When compiling with the changes-meaning flag, syz-codesearch gets a
bunch of errors such as this one:

codesearch.cpp:30:15: error: declaration of ‘clang::SourceRange MacroDef::SourceRange’
  changes meaning of ‘SourceRange’ [-Wchanges-meaning]
   30 |   SourceRange SourceRange; // soruce range of the value
      |               ^~~~~~~~~~~
codesearch.cpp:30:3: note: used here to mean ‘class clang::SourceRange’
   30 |   SourceRange SourceRange; // soruce range of the value
      |   ^~~~~~~~~~~

Let's iron them out early before the code base grows too reliant on
this pattern.
