Jessica Paquette af8e09d4bb [GlobalISel] Add G_LLROUND 
Basically the same as G_LROUND. Handles the llvm.llround family of intrinsics.

Also add a helper function to the MachineVerifier for checking if all of the
(virtual register) operands of an instruction are scalars. Seems like a useful
thing to have.

Add the opcode, docs, and verification.
