Test case ensures lld generates an error if unable to
write an empty index file for lazy object file that is not added to link.
This covers the following line with a test:
https://github.com/llvm-mirror/lld/blob/master/ELF/LTO.cpp#L206
llvm-svn: 336340
We have a following comment for createEmptyIndex caller code:
// If LazyObjFile has not been added to link, emit empty index files.
// This is needed because this is what GNU gold plugin does and we have a
// distributed build system that depends on that behavior.
Though createEmptyIndex() itself
(https://github.com/llvm-mirror/lld/blob/master/ELF/LTO.cpp#L202)
is never called in our test cases.
Patch adds a test.

This should be correctly implied by the linker.
This also makes the tests slightly easier to maintain and compare
with the equivalent tests under for other platforms.
