[x86] Refactor the tests for popcnt.
Extracted from the D6531 patch by Bruno Cardoso Lopes, and re-generated to reflect the current state of the world. This should let Bruno's D6531 actually show the delta between the approaches by running the x86 test case update script after re-building. llvm-svn: 238391
