Currently only two test failures remain on Sparc, both sparcv9-sun-solaris2.11 and sparc64-unknown-linux-gnu:
LLVM :: DebugInfo/Generic/debug-label-inline.ll LLVM :: Linker/subprogram-linkonce-weak.ll
They seem related in that debug info isn't related for inlined functions when LLVM does on other targets.
I've filed separate bugs for both files (Bug 47129 and 47131).
This patch XFAILs the tests.
Tested on sparcv9-sun-solaris2.11 and amd64-pc-solaris2.11.
