440b0e6b34 Don't mark argument value stores as immutable, as otherwise the post-RA

badness. PR8347. Patch by David Meyer

005aa1c020 Teach FileCheck to handle trailing CHECK-NOT patterns. 
A CHECK-NOT pattern without a following CHECK pattern simply checks that the
pattern doesn't match before the end of the input file.

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

fcc42f2f3a 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!

5d5bcb8ee4 Move stack slot assignments into LiveRangeEdit. 
All registers created during splitting or spilling are assigned to the same
stack slot as the parent register.

When splitting or rematting, we may not spill at all. In that case the stack
slot is still assigned, but it will be dead.

acca65b973 Create a new LiveRangeEdit class to keep track of the new registers created when 
splitting or spillling, and to help with rematerialization.

Use LiveRangeEdit in InlineSpiller and SplitKit. This will eventually make it
possible to share remat code between InlineSpiller and SplitKit.

e0b9dbf91b 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.

2c335d364c 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.
