Optimize expanded constant pool words ( #6979 )
...
Re-inline ConstPool entries in V3Subst that have been expanded into
word-wise accessed by V3Expand. This enables downstream constant folding
on the word-wise expressions.
As V3Subst now understands ConstPool entries, we can also omit expanding
straight assignments with a ConstPool entry on the RHS. This allows the
C++ compiler to see the memcpy directly.

Optimize wide word shifts by multiple of word size ( #6970 )
...
V3Expand wide SHIFTL and SHIFTR if the shift amount is know and is a
multiple of VL_EDATA_SIZE. This case results in each word requiring a
simple copy from the original, or store of a constant zero, which
subsequent V3Subst can then eliminate.

Optimize concatenations that produce unused bits in DFG ( #6971 )
...
Concatenations that are only used by Sel expressions that do not consume
some bits on the edges can be narrowed to not compute the unused bits.
E.g.: `{a[4:0], b[4:0]}[5:4]` -> `{a[0], b[4]}[1:0]`
This is a superset or the PUSH_SEL_THROUGH_CONCAT DFG pattern, which is
removed.

Improve combinational cycle fixup in Dfg ( #6744 ) ( #6746 )
...
Now that we have an efficient algorithm to analyse which bits in a
combinational cycle are not dependent on the cycle, can simplify the
cycle fixup algorithms. Remove FixUpSelDrivers: this was a heuristic
to save on the expensive independent bits analysis, but itself can
cause a performance problem on certain inputs that result in a large
number of attempted fixups. Doing this simplifies the driver tracing
algorithm, and because we now only attempt to trace drivers that are
known to be independent of the cycles, it should always succeed...
Unless of course there is a mismatch between the independent bit
analysis ant the driver tracing algorithm. In such case (when we managed
to prove independence, but then fail to trace a driver), we will crash,
which is still easier to sv-bugpoint than a performance bug.
