// function pointer.
// Windows:
// This must be done for each instance of base (i.e. module) and is normally
// chrome_elf!DumpProcessWithoutCrash. See example code in chrome_main.cc that
// does this for chrome.dll and chrome_child.dll. Note: Crashpad sets this up
// for main chrome.exe as part of calling crash_reporter::InitializeCrashpad.
// Mac/Linux:
// Crashpad does this as part of crash_reporter::InitializeCrashpad.
// Returns false if called before SetDumpWithoutCrashingFunction.
//
// This function must not be called with a tail call because that would cause
// the caller to be omitted from the call stack in the crash dump, and that is
// confusing and omits what is likely the most important context.
