    A clang/test/Driver/pseudo-probe.c

  Log Message:
  -----------
  Avoid conflicts between debug-info and pseudo-probe profiling

After D93264, using both -fdebug-info-for-profiling and
-fpseudo-probe-for-profiling will cause the compiler to crash.
Diagnose these conflicting options in the driver.

Also, the existing CodeGen test was using the driver when it should be
running cc1.
