603b8af2eb Don't canonicalize 32-bit FP results in the various pipelines 
It's redundant with the new scheme, so just adds HW for no reason.

cc389bea90 Fix in-register representation of fdiv.s/fsqrt.s result 
We were zero-extending it, which is a double-precision zero in the recoded
format.  So, when spilled and reloaded with fsd/fld, the original value
was destroyed.  Instead, set the MSBs so that it represents sNaN.  When
spilled, the single-precision number will be preserved as the NaN payload.

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.
