[JITLink] Tighten section sorting criteria to fix a flaky test case. (details)

[JITLink] Tighten section sorting criteria to fix a flaky test case. Sections may have zero size and zero-sized sections may share a start address with other zero-sized sections. For the section overlap test to function correctly zero-sized sections must be ordered before any non-zero sized ones. This should fix the intermittent failures in the test/ExecutionEngine/JITLink/X86/MachO_zero_fill_alignment.s test case that have been observed on some builders.
