Move Concat balancing from DFG to FuncOpt (#5602 )

This means it applies more widely, e.g. inside sequential logic.

Split up assignments to wides with Concat on the RHS (#5599 )

Add a new pass to split up (recursively):

foo = {l, r};

into the following, with the right indices, iff the concatenation
straddles a wide word boundary.

foo[_:_] = r;
foo[_:_] = l;

This eliminates more wide temporaries.

Another 23% speedup on VeeR EH2 high_perf. Also brings the predicted
stack size from 8M to 40k.
