r254251 - ARM v8.1a adds Advanced SIMD instructions for Rounding Double Multiply

[James Molloy via cfe-commits]

Ok, understood.

I think I'd be OK with demoting these tests to the test-suite, and dealing
with the slightly lower amount of testing that comes with it if it means we
can keep the clang tests in a nice shape.

We'd need to ensure there were equivalent tests written that test only
clang produced IR - many tests will have this already but some don't.
