Richard Smith 7808c6aa7e Don't use dyn_cast on a Type* which might not be canonical. Fixes an extremely obscure record layout bug.

Andy Gibbs c6e68daac0 Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive.

Eli Friedman 2e108376d5 Recommit r148056 with fixes to deal with weirdness with bitfields in unions. 
Original message: Make sure adding a field to a struct never reduces its size.  PR11745.

Anders Carlsson 446872069f Correctly handle fields with virtual bases containing empty subobjects.

Anders Carlsson 3e88da9fe5 Another empty class layout test.

Anders Carlsson 1ff101cb1a Add more empty class layout tests.

Anders Carlsson 5773205a8d When recording empty subobjects we should always look at the primary virtual base.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Anders Carlsson 7f78d85be4 Start at NextOffset when laying out bases as well.

Anders Carlsson e1883100a3 Who would have thought that empty classes were so tricky? Handle cases where an empty virtual base class needs to be moved aside because it conflicts with the first field.
