One of the features of SME is the addition of streaming mode, in which we
have access to a set of streaming mode SVE registers at the SME vector
length. Since these are accessed using the SVE instructions let's reuse
the existing SVE stress test for testing with a compile time option for
controlling the few small differences needed:
- Enter streaming mode immediately on starting the program.
- In streaming mode FFR is removed so skip reading and writing FFR.
