[PATCH] D34896: Enable the new PM + SamlePGO + ThinLTO testing.

[David Blaikie via cfe-commits]

Does this test any code in Clang? (given the test is being committed
without any change in Clang, I'm guessing maybe not) - perhaps this test
doesn't belong in Clang's test suite?

Looks like changes/functionality in LTOPreLinkDefaultPipeline are tested in
test/Other/new-pm-thinlto-defaults.ll at least?
