8e7ca8e0b1 Don't produce a vtable for a class if we have an explicit template instantiation declaration and no key function. We will produce the vtable at the explicit template instantiation. 
Fixes PR6748

c50c27cca8 the big refactoring bits of PR3782. 
This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

ff6a1fc1f3 Don't produce a vtable if we are just instantiating a method and the 
class has no key function.

Fix PR6738.

85e64359df Flip the switch and use the new vtable layout code for everything. I've verified that this passes a self-host but I'll let the bots self host as well before removing the now dead code.

a627ac7ee6 More vtable work - it's not possible to use the new vtable code for everything by setting a flag inside CGVtable.cpp. My plan is to run some tests and bootstrap and once that's done flip the bit.

800ded68b5 Only add thunks for the most derived class. This fixes some link errors I was seeing in files generated by the vtable tester utility.

848d86e5c4 Make sure to sort the vtable thunks by their vtable index :) With this we now pass the test from http://www.codesourcery.com/public/cxx-abi/abi-examples.html#vtable-ctor successfully.

8baeaf0a26 Two bug fixes, we weren't updating the thunk index when creating the vtable initializer and we weren't storing the secondary virtual pointer indices.

a4147148ff When -fdump-vtable-layouts is specified, construction vtable initializers will be generated using the new vtable layout code. (The code is still not completely in place but this is a huge step forward).
