    [ignition] Change --trace-ignition to a runtime flag · 4becbe34
    Leszek Swirski authored
    Generate the code (extra runtime calls) for --trace-ignition support at
    compile time, based on a #define (similar to TRACE_MAPS). Then check for
    --trace-ignition at run-time when deciding whether to actually print
    anything. This should make --trace-ignition less painful to use.
    
    Note that --trace-igition is disabled by default, even on debug builds.
    It has to be enabled with the gn arg "v8_enable_trace_ignition=true"
    
    As a drive-by, TRACE_MAPS is renamed to V8_TRACE_MAPS, for consistency,
    and SFI unique index (needed both by --trace-ignition and --trace-maps)
    is cleaned up to be behind another #define.
