Mike Stump 2220447adc Ensure we don't output repeated vbase offsets. I have a testcase for 
this, but need to fixup the actual offset value before I can check it
in.  WIP.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between.  Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

// CHECK: 4
// CHECK: 5
// CHECK: 6

would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

Douglas Gregor 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.

Chris Lattner e0be0dfced push GlobalDecl through enough of the CodeGenModule interfaces

get emitted.

Chris Lattner f122cef4df initial support for __[u]int128_t, which should be basically 
compatible with VC++ and GCC.  The codegen/mangling angle hasn't
been fully ironed out yet.  Note that we accept int128_t even in
32-bit mode, unlike gcc.

Douglas Gregor 5fec5b0495 Add basic support for C++ name mangling according to the Itanium C++ 
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.
