Original commit message:

    [compiler] fix CompileFunction ignoring kEagerCompile

    v8::ScriptCompiler::CompileFunction was ignoring kEagerCompile. Unlike
    the other functions in v8::ScriptCompiler, it was not actually
    propagating kEagerCompile to the parser. The newly updated test fails
    without this change.

    I did some archeology and found that this was commented out since the
    original CL in https://crrev.com/c/980944.

    As far as I know Node.js is the main consumer of this particular API.
    This CL speeds up Node.js's overall startup time by ~13%.
