tests: Add a test for the cache write streaming optimizations
The purpose of this regression test is to make sure that optimizations
for write streaming access patterns in the classic memory system
(caches) work as expected.
This test instantiates a simple system, with a traffic generator, a L1
cache and a L2 cache and a simple memory. The traffic generator
performs writes which the L1 cache coalesces and turns into whole-line
writes (WriteLineReq). The effect of write coalescing can be seen in
the stats where the number of ReadExReq accesses in the L2 cache
should be really small, as most requests to the L2 should be
InvalidateReq.
