Rafael Espindola adcc1d18e2 When given the magic class __cxxabiv1::__fundamental_type_info, produce
the typeinfo for the fundamental types.

Fixes PR6685.

Rafael Espindola fa1708fdea revert 99311. Looks like it broke darwin bootstrap.

Anders Carlsson af82f63b47 Always emit associated thunks when emitting the function itself. Remove getVtableAddressPoint, it's not used.

Daniel Dunbar fe06df4bf3 C++: Add support for -fno-use-cxa-atexit.
- So much typing, so little gain...

Also, rename the __cxx_global_initialization function just to match llvm-gcc.

John McCall 7ec5043c2c Change CodeGenModule to rely on the Module's symbol table instead of
shadowing it in the GlobalDeclMap.  Eliminates the string-uniquing
requirement for mangled names, which should help C++ codegen times a little.
Forces us to do string lookups instead of pointer lookups, which might hurt
codegen times a little across the board.  We'll see how it plays out.

Removing the string-uniquing requirement implicitly fixes any bugs like
PR6635 which arose from the fact that we had multiple uniquing tables for
different kinds of identifiers.

Douglas Gregor b14d123774 Give explicit template instantiations weak ODR linkage. Former
iterations of this patch gave explicit template instantiation
link-once ODR linkage, which permitted the back end to eliminate
unused symbols. Weak ODR linkage still requires the symbols to be
generated.

John McCall beec5a080f Implement __builtin_dwarf_sp_column for i386 (Darwin and not), x86-64 (all),
and ARM.  Implement __builtin_init_dwarf_reg_size_table for i386 (both) and
x86-64 (all).

Rafael Espindola 2e42fec3a0 Fix PR6473.
Clang's support for weakref is now better than llvm-gcc's :-)

We don't introduce a new symbol and we correctly mark undefined references weak only if there is no
definition or regular undefined references in the same file.

John McCall 6abe39c61e Create a TargetMachine whenever we create a CodeGenAction. The codegen of
some builtins will rely on target knowledge.

Rafael Espindola 70e040d552 During codegen assert that any copy assignment, destructor or constructor that
we need to synthesize has been marked as used by Sema.

Change Sema to avoid these asserts.

Rafael Espindola c18086ae17 Add support for the weakref attribute. We still produce "alias weak" as llvm-gcc does, but are more strict on what uses of weakref we accept.

John McCall f8ff7b9fd1 Perform two more constructor/destructor code-size optimizations:
1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

command-line option which defaults off.

some failure here that I can't.
