LOG: [ORC-RT] Test basic C++ static initialization support in the ORC runtime.

This tests that a simple C++ static initializer works as expected.

Compared to the architecture specific, assembly level regression tests for the
ORC runtime; this test is expected to catch cases where the compiler adopts
some new MachO feature that the ORC runtime does not yet support (e.g. a new
initializer section).
