    [regexp] Add --trace-regexp-graph · 835f53e4
    Jakob Gruber authored
    Until now we've only exposed trace output for the parse- and assembly
    stages of regexp codegen. Debug tracing of the graph was missing. The
    new --trace-regexp-graph flag fills that hole.
    
    Available regexp codegen tracing flags are now:
    
    --trace-regexp-parser
    --trace-regexp-graph
    --trace-regexp-assembler
    
    The output of --trace-regexp-graph can be formatted with `dot`, for
    example:
    
     $ d8 --trace-regexp-graph [...] | dot -Tjpg -o regexp-graph.jpg
