[PATCH] [ARM] Add tests for default value of Tag_ABI_FP_rounding.

[Tim Northover]

Hi Charlie,

I'm not sure these tests are actually testing what you think they are. the "CHECK-XYZ-NOT" test only applies to the text before the first part that actually is matched. For example

    CHECK-NOT: foo
    CHECK: bar

would match:

    bar
    foo

We probably just need a separate file (though not with every CPU, in my opinion, that's quite a few extra processes).
