Teach FileCheck to handle trailing CHECK-NOT patterns.

A CHECK-NOT pattern without a following CHECK pattern simply checks that the

You can even have only CHECK-NOT patterns to check that strings appear nowhere
in the input file.

ARM instructions that are both predicated and set the condition codes

have been printed with the "S" modifier after the predicate. With ARM's
unified syntax, they are supposed to go in the other order. We fixed this
for Thumb when we switched to unified syntax but missed changing it for
ARM. Apparently we don't generate these instructions often because no one
noticed until now. Thanks to Bill Wendling for the testcase!

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.

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.
