This completes the FIXME listed in FunctionExecutor in regards to deprecating this function. It simply makes the appropriate call into runAndSample and grabs the first counter value. This patch completely removes the function, moving that logic into the callers (currently only uopsBenchmarkRunner). This makes creating new FunctionExecutors easier as an implementation no longer needs to worry about this detail. Reviewed By: gchatelet Differential Revision: https://reviews.llvm.org/D147878
