In the large code model, we now put __chkstk in %r11 before calling it. Refactor the code so that we only do this once. Simplify things by using __chkstk_ms instead of __chkstk on cygming. We already use that symbol in the prolog emission, and it simplifies our logic. Second half of PR18582. llvm-svn: 227519
