a27e853101 diplomacy: move rendering properties to edges 
FlipRendering { implicit p => ... } now changes the render direction of edges.
diplomatic NodeImps can specify a default render flip using the new 'render' method.

fef5054cec diplomacy: disambiguate names only when necessary 
If two (or more) 'auto_' things have the same name, append _0 and _1 to them.

The order of definitions is unaffected; ie:
  a => a_0
  b => b_0
  b => b_1
  c => c
  a => a_1

bc225a4e82 diplomacy: place Monitors inside LazyModules sinks 
We used to place Monitors at the point of the ':='.
This was problematic because the clock domain might be wrong.
Thus, we needed to shove Monitors a lot.

Furthermore, now that we have cross-module ':=', you might not even
have access to the wires at the point where ':=' is invoked.

30c8c8c517 Revert "try to give seqmems clearer names" 
This reverts commit 8db5bbbae0.

This attempt at clarification instead results in confusing generated verilog like:
`dcache_data_arrays_0 icache_data_arrays_0 (...);`
because of deduplication of identically dimensioned SRAMs...

f5bd639863 Don't write badaddr on misaligned fetch exceptions

d93d7b9fa4 Only merge stores that aren't yet pending 
This fixes a deadlock (and possibly memory corruption, though that is
unconfirmed).  The following sequence manifests it, assuming t0
is 32-byte aligned:

    sw t0, 0(t0)
    sw t0, 16(t0)
    lw t1, 4(t0)
    lw t2, 4(t0)
