    [Builtins] Infrastructure for source positions in stubs/builtins · df071e94
    Mike Stanton authored
    Now, the CodeAssembler can annotate Nodes with SourcePositions.
    SourcePositions themselves get a new mode "external," in which
    they get a file_id, line and column. The file_id is currently
    maintained in the isolate, mapping to strings for filenames.
    
    Additionally, inlining information is ignored at this point,
    but in the long run I'd like to recognize calls to different
    CSA functions as manual inlinings.
    
    At this point, if you want to see the results in tools like GDB,
    you'll need to build without clang, and use the GCC toolchain.
    GN flag is_clang=false will do the trick.
