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

Type backreferences for arguments use the DecayedType's original type.
Because of this, arguments with the same canonical type with the same
mangling would not backreference each other if one was a
ConstantArrayType while the other was an IncompleteArrayType. Solve
this by canonicalizing the ConstantArrayType to a suitable
IncompleteArrayType.
This fixes PR23325.

Pointer types in the MSVC ABI are a bit awkward, the width of the
pointer is considered a kind of CVR qualifier.
Restrict is handled similarly to const and volatile but is mangled after
the pointer width qualifier.
This fixes PR18880.

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:
More accurately characterize the nature of array parameters. Doing this
removes false back-reference opportunities. Remove some hacks now that
we characterize these better.

At this point, it's clear that the MSVC mangler uses the type-as-written
instead of the canonical type, so this should bring us closer to MSVC.
The main thrust of this change is to fix the way we mangle decayed array
parameters of function pointer parameters. With a DecayedType sugar
node, this code can now be much simpler.
Fixes PR16096.
This also fixes a separate issue that Richard spotted in review.
Because separate declarations of the same entity can be spelled and
mangled differently, MSVC always mangles the earliest declaration in an
attempt to avoid link errors. Clang now does the same.

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.
