crash when using `-fsanitize=cilk` without `-fopencilk`

[wheatman]

Describe the bug

The following code causes a crash

//crashes with ~/opencilk16/build/bin/clang++  -fsanitize=cilk  del.cpp
// gives a warning with ~/opencilk16/build/bin/clang++   del.cpp

#include <cilk/cilk.h>

int main() {

  int j = 0;

  cilk_for(int i = 0; i < 10; i++) { j++; }

  return 0;
}

if I compile with with ~/opencilk16/build/bin/clang++ del.cpp I get the expected warning about using cilk without specifying a backend

del.cpp:3:5: warning: CodeGen found Tapir instructions to serialize.  Specify a Tapir back-end to lower Tapir instructions to a parallel runtime. [-Wpass-failed=tapircleanup]
int main() {

However, if I include the flag -fsanitize=cilk then I get the warning followed by a crash

del.cpp:3:5: warning: CodeGen found Tapir instructions to serialize.  Specify a Tapir back-end to lower Tapir instructions to a parallel runtime. [-Wpass-failed=tapircleanup]
int main() {

to just get the warning in both cases
