Disable post-ra scheduler for perturbed tests to appease the bots and to
preserve the history of the tests.

We can lower them using our cool tricks if we fpext/fptrunc the second
input, like we do for f32/f64.
Follow-up to r243924, r243926, and r244858.

There's a bunch of code in LowerFCOPYSIGN that does smart lowering, and
is actually already vector-aware; let's use it instead of scalarizing!
The only interesting change is that for v2f32, we previously always used
use v4i32 as the integer vector type.
Use v2i32 instead, and mark FCOPYSIGN as Custom.

We used to legalize it like it's any other binary operations. It's not,
because it accepts mismatched operand types. Because of that, we used
to hit various asserts and miscompiles.
Specialize vector legalizations to, in the worst case, unroll, or, when
possible, to just legalize the operand that needs legalization.
Scalarization isn't covered, because I can't think of a target where
some but not all of the 1-element vector types are to be scalarized.
