Only split around a loop if the live range has uses outside the loop periphery.
...
Before we would also split around a loop if any peripheral block had multiple
uses. This could cause repeated splitting when splitting a different live range
would insert uses into the periphery.
Now -spiller=inline passes the nightly test suite again.

Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on
...
here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.
