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.
