The current llvm.prefetch intrinsic docs state "The rw, locality and cache type arguments must be constant integers." This change: - Makes arg 3 (cache type) an ImmArg - Improves the verifier error messages to reference the incorrect argument. - Fixes two tests which contradict the docs. This is needed as the lowering to GlobalISel is different for ImmArgs compared to other constants. The non-ImmArgs create a G_CONSTANT MIR instruction, the for ImmArgs the constant is put directly on the intrinsic's MIR instruction as an immediate.
