[clang][DebugInfo][test] Convert Objective-C property test to check LLVM IR

[Michael137]

There's a couple of tests like this.

This patch series renames these to something more descriptive and adjusts the tests to check IR. Currently the tests check raw assembly output (not even dwarfdump). Which most likely hid some bugs around property debug-info.
