This patch works towards consolidating all Clang debug-info into the `clang/test/DebugInfo` directory (https://discourse.llvm.org/t/clang-test-location-of-clang-debug-info-tests/87958). Here we move only the `clang/test/CodeGen` tests. The list of files i came up with is: 1. searched for anything with `*debug-info*` in the filename 2. searched for occurrences of `debug-info-kind` in the tests I created a couple of subdirectories in `clang/test/DebugInfo` where I thought it made sense (mostly when the tests were target-specific). There's a couple of tests in `clang/test/CodeGen` that still set `-debug-info-kind`. They probably don't need to do that, but I'm not changing that as part of this PR.
