Log:
[ELF] - EhFrame: add test case to cover uncovered branch of the code.

This test case adds test for the line that was uncovered previously:
https://github.com/llvm-mirror/lld/blob/master/ELF/EhFrame.cpp#L175

it errors out, but we now can test that we have expected flow,
which is different for CIE of version 1 and CIE of version 3.
