Rafael Espindola 0e355701be Bring r325915 back.
The tests that failed on a windows host have been fixed.

Original message:

Start setting dso_local for COFF.

With this there are still some GVs where we don't set dso_local
because setGVProperties is never called. I intend to fix that in
followup commits. This is just the bare minimum to teach
shouldAssumeDSOLocal what it should do for COFF.

Rafael Espindola 5626325f6c Revert "Start setting dso_local for COFF."
This reverts commit r325915.

It will take some time to fix the failures on a windows host.

Peter Collingbourne 0479ca758f CodeGen: Start using inrange annotations on vtable getelementptr.
This annotation allows the optimizer to split vtable groups, as permitted by
a change to the Itanium ABI [1] that prevents compilers from adjusting virtual
table pointers between virtual tables.

Peter Collingbourne 3382b3d801 CodeGen: New vtable group representation: struct of vtable arrays.
In a future change, this representation will allow us to use the new inrange
annotation on getelementptr to allow the optimizer to split vtable groups.

Peter Collingbourne a237fa06fd CodeGen: Use 32-bit gep offsets to address vtable address points.
The relative vtable ABI will use a struct rather than an array as the type
of a vtable. LLVM only allows 32-bit integers as struct indices, so we need
to use 32-bit integers to get addresses of address points. In order to keep
the code simple, we might as well do that unconditionally.

It's probably a reasonable implementation limit to support no more than 2
billion virtual functions per class.

This change causes quite a bit of churn in the test suite, so I'm making
it separately.

Rafael Espindola 8b4659a973 Emit DeferredDeclsToEmit in a DFS order.
Currently we emit DeferredDeclsToEmit in reverse order. This patch changes that.

The advantages of the change are that

* The output order is a bit closer to the source order. The change to
test/CodeGenCXX/pod-member-memcpys.cpp is a good example.

* If we decide to deffer more, it will not cause as large changes in the
estcases as it would without this patch.

Reid Kleckner 70d0d3c4be Cast vtable address points to i32 (...)** to enable more globalopt
We currently use i32 (...)** as the type of the vptr field in the LLVM
struct type. LLVM's GlobalOpt prefers any bitcasts to be on the side of
the data being stored rather than on the pointer being stored to.

Saleem Abdulrasool 1e57f17deb Use the new Windows environment for target detection
This follows the LLVM change to canonicalise the Windows target triple
spellings.  Rather than treating each Windows environment as a single entity,
the environments are now modelled properly as an environment.  This is a
mechanical change to convert the triple use to reflect that change.

1. CHECK-NOT-LABEL is not valid FileCheck.
2. This test would not trigger the CHECK-NOT-LABEL even if 'interface' is
   replaced with 'struct'.
