It is not needed after LLVM r327734. Now it will be easier to copy-paste
IR symbol names from Clang.

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.

Testing has revealed that large integral constants (i.e. > INT64_MAX)
are always mangled as-if they are negative, even in places where it
would not make sense for them to be negative (like non-type template
parameters of type unsigned long long).
To address this, we change the way we model number mangling: always
mangle as-if our number is an int64_t. This should result in correct
results when we have large unsigned numbers.
N.B. Bizarrely, things that are 32-bit displacements like vbptr offsets
are mangled as-if they are unsigned 32-bit numbers. This is a pretty
egregious waste of space, it would be a 4x savings if we could mangle it
like a signed 32-bit number. Instead, we explicitly cast these
displacements to uint32_t and let the mangler proceed.

Summary:
HandleTopLevelDecl on a templated function leads us to try and mangle
it.

Summary:
It seems that __uuidof introduces a global extern "C" declaration of
type __s_GUID. However, our implementation of __uuidof does not provide
such a declaration and thus must open-code the mangling for __uuidof in
template parameters.
This allows us to codegen scoped COM pointers and other such things.
This fixes PR16836.
Depends on D1356.

Template-template arguments appear to be a rather simple encoding of the
template's templated tag type.

Unlike Itanium, there is no code to indicate the beginning of a
parameter pack. I tested this with MSVC 2013, which is the only version
that implements variadic templates so far.
This is needed to compile APInt.cpp for the MS C++ ABI.

Most of the complexity of this patch is figuring out which types get the
qualifier and which don't. If we implement __ptr32/64, then we should
check the qualifier instead of assuming all pointers are 64-bit.
This fixes PR13792.

This includes the following fixes:
- Implement 4 subtly different variants of qualifier mangling and use them
in what I believe are the right places.
- Fix handling of array types. Previously we were always decaying them,
which is wrong if the type appears as a template argument, pointee,
referent etc.
Fixes PR13182.

Do this by making the mangleNumber(APSInt) overload look like
the int64_t version. (The latter should probably just delegate
to the former).
