Merge #11517: Tests: Improve benchmark precision
760af84 Removed CCheckQueueSpeed benchmark (Martin Ankerl)
00721e6 Improved microbenchmarking with multiple features. (Martin Ankerl)
Pull request description:
The benchmark's KeepRunning() used to make a function call for each call, inflating measurement times for short running code. This change inlines the critical code that is executed each run and moves the slow timer updates into a new function.
This change increases the average runtime for Trig from 0.000000082339208 sec to 0.000000080948591.
