D101114 enforced proper version checks, which exposed a variety of version mismatch issues in our tests. We previously changed the test inputs to target 10.0, which was the simpler thing to do, but we should really just have our lit.local.cfg default to targeting 10.15, which is what is done here. We're not likely to ever have proper support for the older versions anyway, as that would require more work for unclear benefit; for instance, llvm-mc seems to generate a different compact unwind format for older macOS versions, which would cause our compact-unwind.s test to fail. Targeting 10.15 by default causes the following behavioral changes: * `__mh_execute_header` is now a section symbol instead of an absolute symbol * LC_BUILD_VERSION gets emitted instead of LC_VERSION_MIN_MACOSX. The former is 32 bytes in size whereas the latter is 16 bytes, so a bunch of hardcoded address offsets in our tests had to be updated. * >= 10.6 executables are PIE by default Note that this diff was stacked atop of a local revert of most of the test changes in rG8c17a875150f8e736e8f9061ddf084397f45f4c5, to make review easier.
