I have merged the 'soft-stop' and 'continue' operations into the 'OnCuIndexOverflow' enumeration. 
I also reused the original 'continue-on-cu-index-overflow' option. When this option is not specified, the operation executes a 'hard-stop'. When its value= 'soft-stop', it generates a 'best effort' DWP file. When its value = 'continue', it continues to generate a DWP file with overflowed offset information.
