I re-generated the affected llc tests, ran the full test-suit on llvm configured for X86 and M68k, and dropped the custom test case which seems redundant. I checked the diff of the llc tests to make sense.

I intend to add another commit that adds pc-relative atomic stores to address the concern that there is no test for the change that removes "direct" pc-relative atomic stores. I intend to add them into llvm/test/CodeGen/M68k/Atomics/load-store.ll .
