[PATCH] D60707: [ARM] Adjust calling conventions for MVE vectors.

[Simon Tatham via Phabricator via llvm-commits]

I think that's unlikely to be too much of a problem, because it exactly mimics the state of affairs for AArch32 NEON, which also does not support arithmetic operations on vectors of two f64s. The existing NEON setup code in `ARMISelLowering.cpp` makes `v2f64` a legal type for argument passing purposes but sets most operations to `Expand`, and my revised version of D60708 <https://reviews.llvm.org/D60708> (which I seem not to have uploaded yet, oops) just modifies an existing `if` statement or two so that exactly the same handling applies to MVE.
