Don't cache the artificial type for the this pointer, there's no difference in the qual type. This is a workaround for the fact that the type isn't artificial but the this decl is, however, we don't have any way of representing it in the current metadata. For now, however, just don't cache the full type. Fixes rdar://10831526 and probably a couple of others. llvm-svn: 150159

// FIXME: The numbers are truly awful.
Generalize DebugInfo tests by avoiding explicit metadata numbers This addresses several (not all) debug info tests that use explicit metadata numbers. Wherever the same number appeared more than once in a test I used a named match to ensure the same number appeared in all those cases (this may still be overly constraining test cases as they may not have actually cared about that relationship). For one-off numbers I just replaced them with an unnamed regex. This may underconstrain poorly written test cases that were interested in checking that certain metadata nodes were related but didn't actually match on all the related nodes numbers. llvm-svn: 174247
