[llvm-dev] New register class and patterns

[Rail Shafigulin via llvm-dev]

I've added a new register class to my target, but haven't used any of the
new registers in any of the instructions. However when I compile llvm I get
the following error:

In SFEQ_ri: Could not infer all types in pattern

Curiously all the instructions where this error occurs are the set flag
instructions (flags like zero, less than, greater than etc).

Would anyone be able to figure out why this is happening? I can provide
more code if needed.
