The pcsections.ll test primarily tests that the AsmPrinter produces the right output in sections. This output is not easily covered by update_llc_test_checks.py, and as such is hand written. This makes maintenance rather burdensome. Instead, let's keep pcsections.ll as simple as possible. Move the more complex tests that primarily test that some atomic operations end up in the PC section to pcsections-atomics.ll. NFC.
