[Hexagon] Add support for "new" circular buffer intrinsics
These instructions have been around for a long time, but we haven't supported intrinsics for them. The "new" versions use the CSx register for the start of the buffer instead of the K field in the Mx register. We need to use pseudo instructions for these instructions until after register allocation. The problem is that these instructions allocate a M0/CS0 or M1/CS1 pair. But, we can't generate code for the CSx set-up until after register allocation when the Mx register has been fixed for the instruction. There is a related clang patch. Patch by Brendon Cahoon. llvm-svn: 328724
