Summary: As discussed in https://github.com/google/oss-fuzz/issues/933, it would be really awesome to be able to use ThinLTO for fuzzing. However, as @kcc has pointed out, it is currently undefined (untested) whether the sanitizers actually function properly with LLD and/or LTO. This patch is inspired by the cfi test, which already do test with LTO (and/or LLD), since LTO is required for CFI to function. I started with UBSan, because it's cmakelists / lit.* files appeared to be the cleanest. This patch adds the infrastructure to easily add LLD and/or LTO sub-variants of the existing lit test configurations. Also, this patch adds the LLD flavor, that explicitly does use LLD to link. The check-ubsan does pass on my machine. And to minimize the [initial] potential buildbot breakage i have put some restrictions on this flavour. Please review carefully, i have not worked with lit/sanitizer tests before. The original attempt, r319525 was reverted in r319526 due to the failures in compiler-rt standalone builds.
