[llvm] cd9142e - DebugInfo: Generalize test/DebugInfo/X86/convert-linked.ll to run with different architectures

[John Brawn via llvm-commits]

Also, despite these tests now using the host triple they only get run when the
X86 target is built (because test/DebugInfo/X86/lit.local.cfg makes them
unsupported when it's not), so these failures aren't showing up in the AArch64
buildbots (e.g. http://lab.llvm.org:8011/builders/clang-cmake-aarch64-quick)
because they don't build the X86 target.
