d1bb82a1f8 Bump chisel3 and firrtl (#566) 
In particular, this bump allows chisel Records and firrtl Bundles to
have fields with names that start with a digit. Mainly effect is
removing the double '_' from trying to have digits as names in Records.

735e4f8ed6 diplomacy: use HeterogeneousBag instead of Vec 
This makes it possible for the bundles to have different widths.

Previously, we had to widen all the bundles passing through a node
to the widest of all the possibilities.  This would mean that if
you had two source[] fields, they end up the same.

5045696f92 TLRational: test all corners 
In order to ensure that verilator is happy, we launch both clocks from a
clock divider.  Sadly, it does not follow the spec wrt.  derived clocks.

See the verilator manual section on "Generated Clocks".

91d1880dbf ClockDivider2: fix launch alignment of clocks (vcs) 
Doing this in Chisel leads to non-determinism due to shitty
Verilog ordering semantis. Using an '=' ensures that all of
the clock posedges fire before concurrent register updates.

See "Gotcha 29: Sequential logic that requires blocking assignments"
in "Verilog and SystemVerilog Gotchas" by Stuart Sutherland, Don Mills.
