In #74514 and #74778 we marked various instrumentation-added sections as large. This causes an extra PT_LOAD segment if using the small code model. Since people using the small code model presumably aren't hitting relocation limits, disable this when using the small code model to avoid the extra segment. This uses Module::getCodeModel() which isn't necessarily reliable since it reads module metadata (which right now only the clang frontend sets), but it would be nice to get to a point where we reliably put this sort of information (e.g. PIC/code model/etc) in the IR. This requires duplicating the existing tests since opt/llc currently don't set these metadata. If we get to a point where they do set the code model metadata based on command line arguments then we can deduplicate these tests.
