84a7e347bf Simplify and fix up the handling of implicit constructors, copy assignment 
operators, and destructors.  Avoids generating declarations/definitions of
trivial constructors/destructors, and makes sure the trivial copy assignment
operator is generated when necessary.

2cefe38365 Fix the offset calculations for non-virtual bases with overrides. 
Refine the VTT entries for virtual bases to refer to the complete
object's vtable instead of constructor vtables.

ff0553ec61 Fix subtle bug in generating LLVM function declarations for builtin functions. 
The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

e8925dbc1d Improve code generation for function template specializations: 
- Track implicit instantiations vs. the not-yet-supported explicit
  specializations
  - Give implicit instantiations of function templates (and member
  functions of class templates) linkonce_odr linkage.
  - Improve name mangling for function template specializations,
  including the template arguments of the instantiation and the return
  type of the function.

Note that our name-mangling is improved, but not correct: we still
don't mangle substitutions, although the manglings we produce can be
demangled.

e0be0dfced push GlobalDecl through enough of the CodeGenModule interfaces 
to allow us to support generation of deferred ctors/dtors.
It looks like codegen isn't emitting a call to the dtor in 
member-functions.cpp:test2, but when it does, its body should
get emitted.

beecd58e21 Explictly track tentative definitions within Sema, then hand those 
tentative definitions off to the ASTConsumer at the end of the
translation unit. 

Eliminate CodeGen's internal tracking of tentative definitions, and
instead hook into ASTConsumer::CompleteTentativeDefinition. Also,
tweak the definition-deferal logic for C++, where there are no
tentative definitions.

Fixes <rdar://problem/6808352>, and will make it much easier for
precompiled headers to cope with tentative definitions in the future.

7dd749e6fd Defer generation of tentative definitions. 
- PR3980.

 - <rdar://problem/6762287> [irgen] crash when generating tentative
   definition of incomplete structure

 - This also avoids creating common definitions for things which are
   later overwritten.

 - XFAIL'ed external-defs.c, it isn't completing types properly yet.
