XDK heap profiler collector

This is a V8 part of the XDK heap profiler patch
From https://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Function_Calls I guess you should do either

    entry = symbols_.Lookup(
        reserved_key_, SymInfoHash(*reserved_key_), true);

or

    entry = symbols_.Lookup(
        reserved_key_,
        ...,
        ...);
