This is the clang counterpart to 208413, which ensures that Homogeneous
Floating-point Aggregates are passed in consecutive registers on ARM.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

An HFA is defined as a struct containing floating point values of the
same machine type. In the 32-bit ABI, double and long double have the
same machine type, so a struct with a mixture of these types must be an
HFA (assuming it meets the other criteria).

Arguments and return values must always be marshalled as for the base
AAPCS when the callee is a variadic function.
Patch by Oliver Stannard!

If HA can only partially fit into VFP registers, we add padding to make sure
HA will be on stack and later VFP CPRCs will be on stack as well.

Lots of tests are using an explicit target triple w/o first checking that the
target is actually available. Add a REQUIRES clause to a bunch of them. This should
hopefully unbreak bots which don't configure w/ all targets enabled.
