    Reland "[stack-trace] Include API functions in Error.stack stack trace" · 193a2617
    Simon Zünd authored
    This is a reland of 3dd56612
    
    The reland introduces a new flag "--experimental-stack-trace-frames".
    The flag is disabled by default, but enabled for relevant tests.
    The flag stays disabled by default until API frames are eagerly
    symbolized to prevent leaks in blink web tests.
    
    Original change's description:
    > [stack-trace] Include API functions in Error.stack stack trace
    >
    > This CL extends Error.stack to include frames of functions declared
    > with the C++ FunctionTemplate API. For example, "print" in d8.
    >
    > Two changes are necessary:
    >   - HandleApiCall and friends need to go through an BUILTIN_EXIT frame
    >     instead of an EXIT frame. The existing stack-trace machinery will
    >     then pick up FunctionTemplate frames without additional changes.
    >   - Turbofan doesn't go through HandleApiCall, but instead uses an
    >     ASM builtin to enter FunctionTemplate functions. A "marker"
    >     frame state is needed to include these frames in the stack trace.
    >
    > Note: This CL only includes these frames in Error.stack,
    > but not (yet) in the stack-trace API (v8.h).
