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.

`id` needs to be handled specially since it is a `TypedefType` which is
sugar for an `ObjCObjectPointerType` whose pointee is an
`ObjCObjectType` with base `BuiltinType::ObjCIdType` and no protocols
and the first level of pointer gets it own type implementation. `Class`
is similar with the `ObjCClassType` as the base instead.
The qualifiers on the base type of the `ObjCObjectType` need to be
dropped because the innermost `mangleType` will handle the qualifiers
itself.
`id` is desugared to `struct objc_object *` which should be encoded as
`PAUobjc_object@@`. `Class` is desugared to `struct objc_class *` which
should be encoded as `PAUobjc_class@@`.
We were previously applying an extra modifier `A` which will be handled
during the recursive call.
This now properly decorates interface types as well as `Class` and `id`.
This corrects the interactions between C++ and ObjC++ for the type
specifier decoration.

When a non-trivial parameter is present, clang now gathers up all the
parameters that lack inreg and puts them into a packed struct. MSVC
always aligns each parameter to 4 bytes and no more, so this is a pretty
simple struct to lay out.
On win64, non-trivial records are passed indirectly. Prior to this
change, clang was incorrectly using byval on win64.
I'm able to self-host a working clang with this change and additional
LLVM patches.

This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.
To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Summary:
MSVC destroys arguments in the callee from left to right. Because C++
objects have to be destroyed in the reverse order of construction, Clang
has to construct arguments from right to left and destroy arguments from
left to right.
This patch fixes the ordering by reversing the order of evaluation of
all call arguments under the MS C++ ABI.
Fixes PR18035.
