John McCall 6936c863b0 Provide an extremely unsatisfactory diagnostic (instead of crashing) when 
mangling an unknown expression kind.  Also conveniently tells the user what
kind of expression they should add to the mangler!

Douglas Gregor eadd3cace9 Eliminate excessive PCH deserialization caused by the search for 
__cxxabiv1::__fundamental_type_info in every translation
unit. Previously, we would perform name lookup for
__cxxabiv1::__fundamental_type_info at the end of IRGen for a each
translation unit, to determine whether it was present. If so, we we
produce type information for all of the fundamental types. However,
this name lookup causes PCH deserialization of a significant part of the
translation unit, which has a woeful impact on performance.

With this change, we now look at each record type after we've
generated its vtable to see if it is
__cxxabiv1::__fundamental_type_info. If so, we generate type info for
all of the fundamental types. This works because
__cxxabiv1::__fundamental_type_info should always have a key function
(typically the virtual destructor), that will be defined once in the
support library. The fundamental type information will end up there.

Fixes <rdar://problem/7840011>.

Chris Lattner be49c03ff4 use the new optimized debug info metadata accessors. In 
addition to the inherent win, this eliminates the pointless
cost of going through the name -> mdkind stringmap that we
were paying.

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.
