Move out the x86-specific tests into tools/perf/arch/x86/tests and define an 'arch_tests' array, which is the list of tests that only apply to the build architecture. The main idea is to encourage developers to add arch tests to build out perf's test coverage, without dumping everything in tools/perf/tests.
