gollvm: add check for '-fsplit-stack' option

On some platforms such as linux arm64, gcc and ld.gold don't support
'-fsplit-stack' option at present, but currently gollvm doesn't check this,
and enters the normal compilation process, then fails when linking. This CL
adds a check for this option when parsing command line options, so that if
'-fsplit-stack' is not supported, the program can exit earlier and report
the corresponding error message.
