aren't actually going to make a normal cleanup for.  Sometimes
we optimistically create branches to such blocks for fixups,
and then we resolve the fixup to somewhere within the cleanup's
scope, and then the cleanup is actually not reachable for some
reason.  The process of resolving the fixup leaves us with
switches whose default edge leads to the cleanup;  we can
replace that with unreachable, then (in many cases) turn
the switch into an unconditional branch.

Fixes PR10467.

A homogeneous aggregate is an aggregate data structure where after flattening
any nesting there are 1 to 4 elements of the same base type that is either a
float, double, or Neon vector.  All Neon vectors of the same size, either 64
or 128 bits, are treated as equivalent for this purpose.  When using the
AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by
expanding them into a sequence of their base types.  This requires extending
the existing support for expanded arguments to handle not only structs, but
also constant arrays and complex types.

This reverts commit 67d097e1232b7d66f58989c16a45b8a11721f76e.
We found a miscompile with ARM byval, which is still being investigated.
In the meantime, this works around the problem by disabling ARM byval.

This was previously not-const only because it has to lazily construct a chain
of ivars the first time it is called (and after the chain is invalidated).
In practice, all the clients were just const_casting their const Decls;
all those now-unnecessary const_casts have been removed.
