John McCall 0710e551ef Record layout requires not just a definition, but a complete
definition.  Assert this.  Change IR generation to not try to
aggressively emit the IR translation of a record during its
own definition.  Fixes PR10912.

Anders Carlsson fcaaa697ec When laying out bases in, always try the "base subobject" LLVM type. If it
turns out that a field or base needs to be laid out in the tail padding of
the base, CGRecordLayoutBuilder::ResizeLastBaseFieldIfNecessary will convert
it to an array of i8.

I've audited the new test results to make sure that they are still valid. I've
also verified that we pass a self-host with this change.

This (finally) fixes PR5589!

Anders Carlsson 58fe1756fb Use a more appropriate LLVM type for the vtable pointer.

Anders Carlsson d681a29ac0 Baby steps towards fixing PR5589. If a class needs a vtable pointer, add one.

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 220bf4fc5a No need to add tail padding if the resulting LLVM struct type will have the same size as the final record size.

Daniel Dunbar 8b57697954 Eliminate &&s in tests.
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

Anders Carlsson cabdeb4932 Use the CGRecordLayoutBuilder even if there are no fields, because in C++ an empty class will have a padding byte.
