[clang][NFC] Make CodeGen/builtins.c cover more architectures (#168319) 
The change made in #162433 exposed a weakness in this test that showed
different results on different archs that were not caught on the CI
bots. This expands the tests to cover more archs, and out of necessity
moves the os_log test into a separate test file.
