f8b45564d1 tilelink: RAMModel must support source reuse 
If a multibeat response comes back, the source might be reused.
If response reordering has made the multibeat response invalid,
we need to remember this even if the valid bit is cleared on reuse.

651da73d89 tilelink: it is now legal to support Acquire for UNCACHED regions 
These cases exist:
  GET_EFFECTS, PUT_EFFECTS, UNCACHEABLE && !supportsAcquire: MMIO
  UNCACHED && !supportsAcquire: speculation ok and may be cached
  UNCACHED && supportsAcquire: LLC/CacheCork applied (slave never probes)
  CACHED, TRACKED && supportsAcquire: slave might probe

9804bdc34e tilelink: remove obsolete addr_lo signal (#895) 
When we first implemented TL, we thought this was helpful, because
it made WidthWidgets stateless in all cases. However, it put too
much burden on all other masters and slaves, none of which benefitted
from this signal. Furthermore, even with addr_lo, WidthWidgets were
information lossy because when they widen, they have no information
about what to fill in the new high bits of addr_lo.

ede87c1f73 tilelink: rewrite WidthWidget beat splitter 
- split the data based on the address, not the mask
  (the first version of TileLink did not have low address bits)
- the dependency on addr_lo is now exposed and easy to replace
