Looks like Paolo already picked up the fix, so this should be fixed
when I get the next kvm pull request.
That said, you might want to make sure the LLVM people know about this too.
The whole "implicit arguments" is a common thing in x86, where lots of
instructions don't need to spell them out explicitly, because of fixed
register allocation (example: divide/multiply instructions only work
with ax/dx as a target etc).
