Douglas Gregor d29fde248e Eliminate an incomplete/incorrect attempt to provide support for C++0x 
unrestricted unions, which ended up attempting to initialize objects
in a union (which CodeGen isn't prepared for). Fixes PR9683.

Chris Lattner 709af79e0a relax this test a bit to hopefully work with VC++

Chris Lattner 117b724b59 keep track of whether being in a RS_StructPointer state 
caused us to skip layout out a function accurately.  If
so, flush the type cache for both the function and struct
case to ensure that any pointers to the functions get
recomputed.  This is overconservative, but with this patch
clang can build itself again.

Chris Lattner d1f1158203 Fix the clang bootstrap and Jay's testcase from llvm-dev by being completely 
conservative when converting a functiontype to IR when in a "pointer within
a struct" context.  This has the unfortunate sideeffect of compiling all 
function pointers inside of structs into "{}*" which, though correct, is
ugly.  This has the positive side effect of being correct, and it is pretty
straight-forward to improve on this.

John McCall 53fcbd2718 Pretty up the emission of field l-values and use volatile and TBAA when 
loading references as part of that.  Use 'char' TBAA when accessing
(immediate!) fields of a may_alias struct;  fixes PR9307.

Argyrios Kyrtzidis 8322b426a5 Amazing that there are still issues with the fields of anonymous struct/unions.. 
Allow taking the address of such a field for a pointer-to-member constant. Fixes rdar://8818236.

John McCall c4094935c0 When emitting an lvalue for an anonymous struct or union member during 
class initialization, drill down through an arbitrary number of anonymous
records.

John McCall bc83b3f011 Be sure to apply initializers to members of anonymous structs and unions 
recursively, e.g. so that members of anonymous unions inside anonymous structs
still get initialized.  Also generate default constructor calls for anonymous
struct members when necessary.

Douglas Gregor 456ad1a817 When a class contains a non-empty anonymous union or struct, mark is 
as non-empty. Fixes PR7021.

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 35dca26835 Fix an assertion when initializing a union using a member initializer. (We weren't casting from the union type to the initializer type correctly).
